1 J. Asi. Soc. Beng. 1873, pt. 2, p. 208, pi. 17, f- 4. 
- Compare with this and macilentus the IT. Shurtleffianus of 
Lea (J. Ac. Philad. n. s. vol. 3 (Ohs. U. vol. 6), p. 23, pi. 27, f. 
17). from Nagpore, and with this and cseruleus his U. evitatus 
(Obs. II. vol, 12, p. 39, f. 92). 
3 Morch regards the IT. trimcatus of Spengler as a form of 
this most variable species. 
' Compare with this the tripartitns of Lea (Proc. Philad. 
1863), from the river Jellinghur. 
5 The trirostris of Peeve seems cseruleus, to which species 
the semiplicatus of Troschel (Wiegm. Arch. Nat. 1837. p. 180), 
if a Unio at all, for the description reminds one of Novaculina, 
may possibly belong. 
6 Limas and Parmacella have been omitted for want of 
materials : according to Benson's manuscript the Vitrina baccata 
of Hutton is the fry of P. rntella. Our work being to illustrate 
shells, not mollusks, the rudimentary Heliearion Theobaldi of 
G. Austen (Proc. Z. 1872) and his H. croceus (517, pi. 30, f. 9) 
have been emitted. So poor are we for space. 
7 J. Asi. Soc. Beng. 1870, vol. 39, pt. 2, p. 401. From near 
the river Ataran, Martaban. 
5 In Appendix to Index Moll. Chr. Fred. p. 1. Reeve 
(Conch. Icon. Vit. f. 67) has figured what may possibly be the 
fry of a species described as twice or thrice the size of Aude- 
bardi. The plate referred to by Pfeiffer and Reeve has not been 
issued ; indeed very few copies of even the Appendix were dis- 
tributed. 
9 An. Nat. His. 1853, ser. 2, vol. 12, p. 93. Ceylon. 
10 J. Asi. Soc. Beng. 1871, vol. 40, pt. 2, p. 44, pi. 2, f. 7 (as 
Heliearion). Darjiling. 
11 Our figures precisely represent the type of the V. auriformis 
of Blanford (J. Asi. Soc. Beng. 1865, vol. 36, pt. 2, p. 36) from 
the Nilgherries. 
12 See, too, J. Asi. Beng. 1875, t. 2, f. 5. In that plate are 
delineated, also, Heliearion Shillinghense, brunneum and Na- 
gaense, the shields of which hardly merit to be called shells 
13 In addition to those in our list we roust specify the African 
H. Perotteti of Pfeiffer (Reeve and Kuster’s figures are very 
unlike), and the Singapore H. l_\chnia of Benson, both ascribed 
to the Nilgherries, the Nanina fragilis of Hutton, which is most 
inadequately (J. Asi. Beng. vol. 7, p. 216) defined. Compare 
with our minute trochiform species the H. (Kaliella) peliosanthi 
of Morch (Aftryk. Nat. Kjobenhavn, 1872) from Calcutta, which 
w r e have not seen.
