202 PUPILLA, ASIA. 



Moellendorff states that Andreae's Pupa signata, as figured 

 by him from localities in Gaii-su (in Futterer's Durch Asien, 

 iii, 1911, Land u. Siisswasserschnecken, p. 71, f. i, loess of 

 Thung-fan yi and other places in northwestern China), is 

 identical with P. h. grandis. It is distinctly swollen, while 

 sigiiata is strictly cylindric ; on the right margin of the peri- 

 stome there is a strong tooth-like thickening which is lacking 

 or scarcely indicated in P. signata; there are besides differ- 

 ences in the teeth. He does not doubt that signata is to be 

 deleted from the Chinese fauna, and that if intermediate 

 forms are perhaps found in central Asia we can apparently 

 separate the signata-interrupta-heudeana series only subspe- 

 cifically. 



Andreae's figures show no palatal plica?. They are repro- 

 duced in pi. 22, figs. 8, 9. 



(Indian species) 



There is at present no satisfactory evidence that Pupilla 

 lives anywhere in the Oriental Region. I have seen P. annan- 

 dalei only; my knowledge of the other Indian species is 

 secondhand. P. eurina appears to be a true Pupilla, but the 

 river-drift specimens probably floated down from places well 

 within the limits of the Paltearctic fauna ; the inclusion of 

 these two species in the Indian fauna is an accident of polit- 

 ical boundaries. Nobody in this generation seems to have 

 seen seriola or diopsis; they are probably not Pupillas, but 

 without seeing them, no opinion of value can be formed.

The shell is rimate, cylindric, with short, convexly conic 

 summit and obtuse apex, the last 3 whorls about equal in 

 diameter but regularly increasing in height. First li/o whorls 

 having a close, minute but very distinct thimble-like pitting; 

 following whorls with fine but strong, nearly straight, very 

 oblique striation, the strife nearly as wide as their intervals. 

 The whorls are rather strongly convex, the back of the last 

 flattened and tapering downwards, deeply furrowed over the 

 lower-palatal fold, a little swollen and then abruptly con-
