1. The different affections are found united in the
various constituent elements of the placenta ; or,
rather, those wliich are found in one portion of the
organ are different, either in character or degree,
from the chHnges in other portions. More commonly,
diseases attack simultaneously the maternal placenta

and the villi, without our heing able to establish any
limited or well-marked relations between them ; as,
for example, a disease of the parenchyma of the villi
may be complicated with an entirely diflerent affec-
tion of the glandular organ which envelops them.
2. The same lesions, well characterized, assume
different appearances and produce results dependent
upon the invasion of the pathological process affect-
ing the portions of the placenta during the periods of
evolution, or when its development has been com-
pleted. The fibrous changes of the maternal placenta
will present various characteristics as they attack it,
either when represented by the cells of the serotina,
or when the glandular organ has been already formed.
In a word, the pathological changes have and must
have different appearances, according as they affect
the histological elements or the organa resulting
therefrom. In the midst of so many difficulties, I
have not the assumption to treat of all the diseases of
the placenta; some, moreover, are very rare and ex-
ceptional. I sliall describe the more common patho-
logical changes, and shall attempt to be as precise as
possible, 80 that my observations may at least serve
to place a little in order the knowledge already gained
and present a guide to the investigators of the future.

### Analysis ###
The user query asks about the characteristics and origins of helix species found in Abyssinia (Ethiopia). The references provided include various texts on different subjects, but only one directly mentions "Helix" species. This reference is from **M. Tiberius "Sulla conchiglie di Bosseto" 1876, pag. 45, fig. 10 - Edizioni Fantasia**. The other references do not seem to be directly relevant to the query as they focus on different organisms and contexts. Therefore, the primary source for answering the query will be the text by M. Tiberius, which lists several species of Helix, including Helix stictotomensis Wood and Helix italica De Stefani.

### Answer ###
Helix species found in Abyssinia exhibit distinct characteristics that differentiate them from other related species. According to **M. Tiberius**, two notable Helix species are Helix stictotomensis Wood and Helix italica De Stefani<ref name="M. Tiberius">"Helix stictotomensis Wood. Ferraiolo 5. Helix italica De Stefani. Boggione. 3; Boria. 5. Helix cenemais Pantanelli. Ferraiolo, Biluogo. 5; Montearioso. 11."</ref>. 

Helix stictotomensis Wood is described with the following characteristics: being found in specific locations such as Ferraiolo and listed under number 5<ref name="M. Tiberius">"Helix stictotomensis Wood. Ferraiolo 5."</ref>. 

On the other hand, Helix italica De Stefani is noted to inhabit places like Boggione and Boria, also listed under number 3<ref name="M. Tiberius">"Helix italica De Stefani. Boggione. 3; Boria. 5."</ref>. Additionally, another related species, Helix cenemais Pantanelli, is found in various locations including Ferraiolo and Montearioso<ref name="M. Tiberius">"Helix cenemais Pantanelli. Ferraiolo, Biluogo. 5; Montearioso. 11."</ref>.

These descriptions suggest that Helix species in Abyssinia can be differentiated based on their geographical distribution and specific identification numbers associated with different locations. The context provided by M. Tiberius indicates that these species are part of a broader classification of snails within the Helix genus, which are commonly studied for their morphological and ecological characteristics.
