MOLLUSOA OF INDIA. 213 
position of such fragments of these curious accessory organs as L 
have found from time to time when dissecting these spirit speci- 
mens, and which I have figured on Plates XXVIII., XL., and LXI. 
The spermatophore in this species consists of a very elongated bag 
17 mm. in length, with a hard papillate head, fining out to a thin more 
or less bent rod. This bag or sack narrows gradually at the 
basal end, and is inserted into a long, hard, chitinous portion, 
which can best be likened to a long piece of house-guttering, which 
instead of being straight is curved, both sides of the gutter being 
fringed as it were with bifid spines. It is this hard portion which 
is commonly preserved and which one generally finds more or less 
broken up into short lengths. ‘The pattern of the spines it is seen 
varies in different species, and gives us another character. 
The Odontophore. The teeth are arranged thus :—

The central teeth tricuspid, as in the genus; the median bicuspid, 
the inner tooth much the longest. The outermost laterals very 
minute, bicuspid. Thus we find that although the generative organs 
are like species of Oaytes, the odontophore follows the type of 
Macrochlamys. The jaw has a large central projection on the 
concave side. 
I have now before me six examples from Tundiani, near Murree, 
sent me by Mr. Theobald, the same as those referred to by him in 
his paper on the shells from that place, published in 1881. They 
are minutely, regularly, and spirally striate under a lens (like fig. 9, 
Pl. XXI.), the strize being very sharply defined. He named them 
H, austinianus ; but I consider they are only the young of M. 
flemingi. The description of the animal, which is that of a Ma- 
crochlamys, is fortunately given. The animal is furnished with a 
large mucous pore behind, and carries a long linguiform process of 
the mantle capable of extension to the apex, and is one of those 
species which, though so provided, does not possess a polished shell*. 
The texture of the shell (epidermis) is during life delicately 
sericeous, from the fine striation of the epidermis. 
Size: maj. diam. 17:0, min. 13°8, alt. axis 7°0 mm. 
Colour olive-green or olivaceous brown. 
Macrocutamys attivacus, Theobald. (Plate LIV. figs. 2, 2 a.) 
Helicarion flemingit, var. altivagus, Theob. J. A. S. B. 1878, 
p. 143. 
Locality. Uri, Jhelum valley, below Baramula Kashmir (coll. 
Theobald). 
Original description :—* Of this form I have only a few dead 
shells. The largest measures 31 x 23 x 14 mills., and it differs 
from the type by being much flatter. Ionly met with it sparingly 
above Uri.” 
* Compare this description with that of H. flemings, var. b, given in the 
J. A. 8. B. 1878, p. 143, which is certainly another species and genus.
