unites with the penis is the thin capsule also spined down the 

 side, the spines being bifid and arranged in sets o two together. 



The radula was similar to other species of the genus, arranged : 

 + 40 . 2 . 12 . 1 . 12 . 2 . 40 + 



+ 54 . 1 . 54+ 

 Some of the outermost laterals not seen.] 



Major diarn. 12, min. 10, axis 6-5 mm. 



Hob. Watawala, Ceylon (Cottett). 



Distinguished from E. emiliana by fewer whorls, much more 

 prominent keel, nmcn'rouuder and higher mouth, and by the body- 

 whorl being considerably more tumid beneath the keel.

Shell perforate, turbinate, sharply keeled, thin, horny, trans- 

 lucent, finely costulate above, each rib bearing about 10 elongate 

 granules, separated by equidistant impressed spiral lines, lower 

 surface polished, radiately striated ; spire conoidal, apex acute ; 

 whorls 6, slightly convex above, the last with a sharp compressed 

 keel, convex beneath ; aperture slightly oblique, angularly lunate ; 

 peristome thin, basal and columellar margins curved, the latter 

 reflected throughout, more broadly above. 



Major diam. 14, min. 13, axis 8 mm. 



Ha'b. S.W. Ceylon (Thwaites), Uda Pussellawa, Watawala (Col- 

 lett) ; Fort McDonald (H. Nevill). 



This has a much higher spire than E. emiliana, and there are 

 fewer spiral impressed lines, about 10, on the last whorl. Pfeiffer's 

 description was taken from half-grown shells, and these have been 

 figured by Reeve and Hanley. The above description is from 

 adults in Mr. E. E. Sykes's collection. Specimens from Fort 

 McDonald have a white keel. 



94. Euplecta fluctuosa, Blf. Proc. Mai Soc. iv, 1901, p. 251, fig. 1. 



Shell subobtectly perforate, turbinate, carinate, pale horny, 

 closely and finely ornamented throughout with flexuous transverse 

 rows of granules arranged in spiral lines, the lower surface smooth, 

 decussately striated ; spire conoid, apex obtuse, suture impressed ; 

 whorls 5, convex, the last compressedly keeled, convex below ; 

 aperture diagonal, approaching a rhomb in form, margins con- 

 verging slightly ; peristome thin and in one plane, columellar 

 margin triangularly reflected. 



Major diam. 11 1, min. 10 j, axis 7 mm. 



Hab. Gaisoppa Falls, North Canara. 



This shell is distinguished by its peculiar flexuous and granular 

 sculpture, few whorls, and diagonal aperture.
