Among the fossils submitted to me for determination at dif- 
ferent times by Mr. Cunningham-Craig, latel}' Government Geol- 
ogist, was one collection of peculiar interest consisting of fresh 
water shells of Genera and species not now found in Trinidad 
and forming a fauna completel}’ distinct from an\" now existing 
here. The locality given me was Comparo Road. I furnished 
Mr. Craig with the names of the shells and notes on them ; but 
as I have already waited some con.siderable time and it may be 
long yet before anj’ general paper b}' him appears I think it as 
well to put on record the names of these fossils. 
I. Hemismics sulcatus, Conr. 
Amer. Journ. Conch. 1870. 
Conrad a.ssigns H. tenellus as a near ally of this shell. It is 
however ver}’ closel}^ akin to H. bicinctus Reeve an existing spe- 
cies of South American Riv^ers. Melania cingulata Moricand 
(Journal de Conch, i860, PI. xii F. 6) and M. {Melanopsis) bra- 
siliensis Mor. (Ibid. PI. xii, F. 7.) are also very near. 
2. Leptoxis crefiocarina , Myricand. 
An inhabitant of Brazilian rivers. A remarkable and aber- 
rant form of Melania. 
3. Anodon batesii. Woodward. 
Ann. and Mag. M. H. 1871-4 Ser. Vol. vii. P. 103 PI. v. F. 10. 
There is no need to go to Asia for the nearest Analogue of 
this Bivah'e, which is related to the Anodon Leoiaudi of our 
Rivers and equally so to sirionos Orb. and A. puelcliana Orb.
