(Collett). A specimen has also been received from Kegalla through 

 the kindness of Mr. Hugh B. Preston.

Hah. — Travancore Hills, South-West India. 



This may be differentiated from the previous species by its much 

 greater size and the comparatively larger orifice in the mantle : 

 the mantle keels, though present in the younger examples, become 

 indistinct on the adults. The colour is either uniformly ochreous, 

 or this is dotted with black blotches all over the mantle and on 

 the sides behind it, while one wholly black specimen is recorded 

 and figured by the original describer. The keel on the foot was 

 found with one exception to be dark-coloured. The shell appears 

 to be, comparatively, somewhat narrower than in M. Bussumieri, and 

 is convex below, the original hollow being filled up ; while the 

 longitudinal striation of the jaw is not so well marked as in that form. 

 The central tooth of the radula is tricuspid ; the marginals have 

 a step-like ecto-cone, a large meso-cone, and hardly any apparent 

 ento-cone : the transition into typical laterals is much more gradual, 

 as might be imagined from the fact that the ecto-cones are much less 

 strongly developed to begin with than in the last species, and 

 consequently it takes a larger series to reach the more uniformly 

 bicuspid type ; in fact, in but few of these does the ecto-cone exceed 

 the meso-cone in size. 



The dart sac (PI. IX, Fig. 7) is more elongated than in the other 

 species, and is longer than the spermatheca, while the swelling of the 

 free oviduct is more marked. 



With respect to the so-called Tennentia Philippinemis^ Semper, 

 already spoken of, and two other species recently described from 

 the Philippines under the same generic name, viz., Maricella carinata, 

 Mlldf., and M. Quadrasi, Mlldf., Mr. W. E. Collinge says that 

 Dr. von MoUendorf writes to him — "I have my doubts if all 

 three really belong to Tennentia.'''' 



Under these circumstances, and taking into consideration the fact 

 that the two latter ' species ' were described ^ in a dozen lines or 

 so, without figures, from external examination of single specimens, 

 the writer does not at present feel justified in including them in the 

 list of valid species of Maricella.
