IIOLLUSCA or INDIA, 285 



description from life in his Field Note Book. It must be 

 remembered that in 1861 only a few Indian species had been 

 examined externally, of not one was the internal anatomy known ; 

 neither is it easy in life, when the animal is swollen, exuding 

 mucus, and on a hasty examination, to take in the form of the 

 shell-lobes, which is now done for the first time.

" Shell subobtectly perforate, subturbinately depressed, thin, 

 smooth, polished, minutely and closely stx'iated concentrically 

 (longitudinally) throughout beneath the microscope, rufescent 

 brownish horny ; spire conoid, apex acute, suture impressed ; 

 whorls 6, convex, the last considerably broader, rounded at peri- 

 phery, convex below ; aperture subvertical, roundly lunate ; 

 peristome thin, basal margin slightly arcuate, columellar curved, 

 vertical above, triangularly reflected partially covering the per- 

 foration. 



" [' Animal of Nilgiri specimen very similar to II. vitrinoides

 processes to the mantle. Back very narrow but not keeled above.

Animal (figs. 1 «, 1 h) of a very blue-black colour throughout ; 

 sole of the foot divided, the central area very pale, contrasting 

 strongly with the very dark margins ; a large lobe above the 

 mucous pore ; peripodial margin closely fringed, the peripodial 

 grooves above, the furrows leading from them to the rounded keel 

 of the foot wide apart, the intervening surface of the integument 

 rather smooth ; the thin wall of the branchial sac indigo-blue, the 

 veins conspicuous being bordered by thin black lines. The right 

 shell-lobe is moderately long, given off from below the upper 

 inner angle of the aperture, it is thin and smooth, and elongately 

 leaf-like when expanded, not at all like that of Macrochlamt/s, 

 which is narrowly tongue-like tapering to a point and crossed at 

 right angles by lines of its muscular conti-action. The left shell- 

 lobe is much broader and leaf-like, smooth, not in the least 

 papillate. The right dorsal lobe is small ; the left is in two parts, 

 close adjacent, the anterior small, the posterior narrow.
