104 Contributions to Indian Malacology. [No. 2, 
although I probably possess the former, I am totally unable to tell, 
from Mr. Theobald’s account, to which of the numerous varieties of 
H. rotatoria he has applied the name. Again, in this paper as in 
former ones, manuscript names are introduced without any reference 
to the fact of their being unpublished ; and, in two cases at least, I 
believe I can shew that these names would never have appeared, had 
they not been cited by Mr. Theobald. 
Ist. A. wnicincta was a manuscript name of Mr. Benson’s for a shell 
from Western India, described by Pfeiffer as H. propinqua. Mr. Ben- 
son’s name of course was never published, nor would it have seen the 
light but for Mr. Theobald, who, in his paper in 1863, gave H. uni- 
cincta as a species excluded from his list, without referring to the fact 
that no such name existed except in manuscript. In the present 
paper, H. propinqua, Pfr, is first given as a distinct species, and a 
few lines further on quoted as a synonym of H. unicincta ; thus 
giving precedence to the manuscript name, in opposition to the laws 
of scientific nomenclature. 
2nd. H. anoplewris was a manuscript name given by Mr. Benson to 
some shells sent by Mr. Theobald to England, I believe in 1860 or 
1861. Mr. Theobald having kindly furnished me with specimens of 
the same shell, I found, on comparing them with the types of H. orna- 
tissima, Bens., of which I had a good series, (the shell was first col- 
lected by my brother and myself and described from our specimens) 
that the species were identical in every respect. I wrote to Mr. Ben- 
son to tell him my opinion and on recomparing the forms, he found 
that he had been misled by an abnormal peculiarity in the solitary 
specimen of H. ornatissima which he had retained. 
Another name mentioned by Mr. Theobald, Heliw submissa, Bens., 
is equally, so far as [ am aware, undescribed. 
In the group placed by Mr. Theobald next after that in which the — 
above shells are included, there is evidently a misprint, in the five 
shells from H. infrendens, Gould, to H. sanis, Bens., being classed 
together. I have no doubt Mr. Theobald’s intention was to class — 
together the three first, and, as a separate species, the two last.* 
* J am authorized by Mr. Theobald to notify that this error was due to a 
misinterpretation of his manuscript. His intention was that suggested in the 
text. Hp,
