 14 (1854), p. 413.— Pfeif. Mon. Pneum. vol. 2, 

 p. 45. 



Darjiling ; Sikkim Himalayah. 



2. C. affinis, Theobald. See pi. 2, f. 7. 



The peculiarity of lip referred to by the author was 

 simply accidental. The individual here represented, 

 which reminds one of a dwarf carinated Siamensis, is 

 almost the only one known to us, the supposed second 

 example alluded to having proved to be distinct. 



3. C. Indicus, Pfeiffer (as of Deshayes), Mon. 

 Pneum. vol. 1. p. 77 (from Cuming's collection) ; 

 Kuster, ed. Chemn. Cycles, pi. 33, f 3, 4 (as 

 Cyclostoma). 



Isle of Elephanta, near Bombay. 

 It may be doubted Avhether this can be the Cyclo- 

 stoma Indicum of Deshayes in Belanger's Voyage 

 (Zool. Moll. pi. 1, f. 4, 5), the lower face of which does 

 not suit any example we have seen.

Shan States. 



The previously recorded locality was Pulo Penang. 

 The Cyclostoma volvulus of Souleyet (Voy. Bonite, 

 Moll. pi. 30, f. 18-21) is considered by Pfeiffer to be 

 identical. 



5. C. Pearsoni, Benson. See plate 1, £ 6. 



We have figured Benson's type, which displays no 

 traces of that articulated keel which forms so pro- 

 minent a feature in the next species. 



6. C. Haughtoni, Theobald. See plate 1, f 3, and 

 plate 3, f. 6. 



A characteristic form. In our previous figures the 

 articulation was inadequately represented, few, if any, 

 traces of it having been visible upon the portion de- 

 lineated, though freely developed upon the opposite 

 side.
