FAUNA OF THE KARNUL CAVES. 67 
VI. MOLLUSCA. 
General . — For the determination of the very few shells obtained from the Karnul 
caves the writer is indebted to Mr. W. Theobald. The five species which have been 
determined are all found at the present day in the same region. Several of the 
shells still retain distinct traces of their colouration. 
Helicidce. — Of Helix (including subgenera) there are three species, namely II. 
( Ariophanta ) cysis , Benson, II. ( Hemiplecta ) vitellina, Pfeiffer, and II. ( I o tula) indica, 
Pfeiffer; while Bulimus is represented by B. ( Cylindrus ) insularis, 1 Ehr. Specimens 
of the first three species have been obtained from beds C and Ca in the Cathedral, 
while the one specimen of the last is from the Charnel-House. 
Cyclostomidce. — This family is represented by Cydopliorus involutus (Mull.), which 
appears commoner than any of the other species. Mr. Theobald remarks that the 
Karnul shells are not of the Ceylon type, but agree with the variety now found 
living at Midnapur, in Bengal. 2 Some of the fossil specimens were obtained from 
the Charnel-house and others from bed Ca in the Cathedral cave. 
ADDENDUM. 
The following specimen was overlooked until the text was in type. 
Herpestes nipalensis, Gray. 
Mandible . — The imperfect right mandibular ramus of a small species of Herpestes 
from bed Cb in the Cathedral represented in 
the accompanying woodcut may be referred 
to the present species. The specimen shows 
the broken canine, the complete mTI, and the 
alveoli of the other cheek-teeth. The speci- 
men agrees precisely with the jaw of the 
existing race ; the large size of the alveolus 
of pm. 1 distinguishing it from the allied 
African H. gracilis , in which this tooth is either wanting, or of much smaller size 
than in H. nipalensis. 
Distribution. — At the present day the species occurs throughout the outer Hima- 
laya, and also in the plains near the hills from the Punjab to Bengal, as well as 
in Assam, Burma, and the Malay Peninsula ; the extension of its range during the 
pleistocene into southern India is paralleled by that of Rhinoceros unicornis.

2 Mr. Theobald says that the shell figured in Hanley and Theobald’s “ Conchologia Indica,” pi. II. fig. 8 as from 
Midnapur does not represent the form obtained there by himself, which is the same as the fossil one.
