Tcnnmtia phUippincnm^ sp. n.. Semper, 1. c. p. 7, pi. 1. figs. 16, 16, repre- 
senting the living animal, Mindanao; genital apparatus, jaw, and radula of 
the same, pi. 3. fig. 1, and pi. 6. fig. 17, the latter differing by its simple 
median tooth from that of the typical species, T. thwaitesn^ Humbert. The 
genus Mariadla (Gray, 1865) is probably identical, and has in that case 
priority. Semper, 1. c. p. 8.

fig. 2, and pi. 6. figs. 11, 12. — The African species, P. Jlavcscens (Keferstoin), 
differs by its lateral teeth being unicuspid instead of bicuspid, and belongs to 
Urocyclus, Gray. — P. extraneus, F^r., from Calcutta, figured from a specimen 
in spirits, pi. 1. fig. 5. — The following species, known only from the shell, 
belong probably to this genus : — Vitrina papillata, Pfv., planata, Pfr., apertay

Helicariony F^r. C. Semper characterizes this genus anatomically by the 
want of an appendicular gland in the vagina and a peculiar sac containing 
calcareous concretions at the vas deferens ; he introduces into it, from his 
anatomical researches, several species, the shell of which agrees much more 
with that of Helix than with that of Vitrina^ and arranges them in two 
series. 
a. Species which have peculiar horny papillae in the lumen of the penis. 
To this series belong all Philippine species. They live on trees, and when 
disturbed the hinder part of their foot is lost by vehement wriggling. They are : 
— 11. ccratodcs, Vit.,gutta, Beck, hclicoidcs, sp. n., Oamiguin, crenularisy Beck, 
resiliens, Beck, inceidus, sp. n., island Cebu, Philippines, margaritay Beck, tigri-

Of all these species the genital apparatus and the dentition are described, and 
the one or the other figured on pi. 4 and pi. 6. Several other Philippine species.
