Pachylabra virens (Lamarck). 
1912. Pachylabra maura, Kobelt, op. cit., p. 85, Taf. 
xyxv, fig. 2; and P. paludinoides Kobelt (nec 
Chr. and Jan.) in part, p. 102, Taf. xl, fig. 6, 
and xiliii, fig. 3. 
Kobelt’s account of this species based on Reeve is far 
from complete. He, as I have pointed out already, mistook 
one of the shells of this species for P. largillierti; and has 
altogether missed out the forms virens, Lam., carinata, Swain., 
and malabarica, Phil., all of which, however, are only 
synonyms of this species. 
It is of interest to note here, that the shell from the 
Miinchen Museum, figured by Kobelt (Taf. xl, fig. 6) as pro- 
bably the type-form of P. paludinoides (Phil.) is also a speci- 
men of this species, and so is also the fig. 3 (Taf. xliii) copied 
from Reeve; only this specimen is a little more globose than 
is normally the case. The species, however, has a very wide 
range and varies greatly in the form of the shell. 
In addition to the specimens of this species noted in 
accounts of the other species, other are in the Senckenberg 
Museum two typical specimens from Madras, India, labelled 
Ampullaria carinata var. malabarica, Phil. 
Pachylabra theobaldi (Hanley). 
1912. Pachylabra theobaldi, Kobelt, op. cit, p. 86, Taf. 
MxXv., fig. 1. 
Kobelt had a young specimen of this beautiful species 
from Boettger’s collection from Moulmein, Burma, lled 
Ampullaria paludinoides, Christ., but he apparently did not 
recognize the species. He has included the description from 
Hanley’s original account of the species, and copied the figure 
from ‘“ Conchologia Indica.” He does not make any reference 
to Pilsbry’s Burmese species A. winkleyi, | which, however, 
seems to have been based on only young shells of this species. 
Pachylabra conica (Gray). 
1912. Pachylabra conica Kobelt, op. cit., p. 93, Taf. xl, 
figs. 1- ; 
identification of this species and its varieties has 
ian a confused by Kobelt, who in his notes has mainly 
followed Reeve and Sowerby. The figure of the typical form 
copied from Reeve as fig. 1 (Taf. xl) is a correct representation 
of the typical form. His figures 2 and 3 are of a Javanese
