959. Mr. MPA: Smith and Mineweb abroster on 
the ovary. But it does not agree with Cnemidocarpa in 
other respects, even as regards the gonads. Cnemidocarpa 
has from few to many gonads, which are usually straight or 
tortuous. Ypsilocarpa has, on each side, only one gonad, 
which is of considerable length and bent in the shape of the 
letter U. Such essential differences in the reproductive 
organs forbid its inclusion in the genus Cnemidocarpa as now 
defined. 
Since the classification of the Styelide is principally based 
on the peculiarities of the reproductive organs, a new genus 
should be established for the species here described. The 
other important anatomical differences further justify this 
course. 
The genus Ypsilocarpa is therefore defined as follows :— 
Branchial sac.—Four folds on each side; three are well 
developed, and one—the second—is in a rudimentary 
state. : 
Gonads.—One elongate cylindrical gonad on each side, bent 
into the shape of the letter U, and made up of both 
ovary and testis. 
Atrial tentacles—The atrial tentacles are thickly scattered 
over the narrow velum. . 
Genotype.— Ypsilocarpa clipeata, with the same diagnosis. 
The surface of the test is divided into polygons. 
XL.—On a Collection of Reptiles and Batrachians from the 
Island of Ceram, Indo-Australian Archipelago. By 
Matcotm A. Smiru, F.Z.S8., and Joan B. PROcTER, 
F.Z.S. 
AMONG a small coliection of reptiles and batrachians recently 
submitted to us for examination at the British Museum of 
Natural History there appears to be a new snake of the 
genus Typhlops and a new race of the frog Rana grisea, 
van Kampen. 
Other species in the collection are also worthy of record, 
either because they increase the range of their known distri- 
bution or because they show some variation in character from 
the published description.
