814 MR. E. A. SMITH ON MARINE SHELLS [Nov. 5, 



is variegated with fine white zigzag lines and small brownish spots, 

 principally on the upper edges of the transverse lirse. The superior 

 margin of the upper purplish-brown band is interrupted by opaque 

 white blotches edged on one side by dark brown. In the Monograph 

 of this genus (Thesaurus Conchyl. iv.) Sowerby cosiders this species 

 a variety of M. incisa, Ad. & Reeve. However, I think there are 

 sufficient differences to separate them. The form of the latter is 

 narrower, the whorls proportionally higher, the transverse ridges on 

 the spire flatter, and the spire itself is less acutely conical.

Hab. Zanzibar (Reeve). 



The plaits on the columella are not invariably five in number, some 

 specimens being furnished with a sixth. The shells from the Anda- 

 man Islands have less of the brown markings than appear in Reeve's 

 figure, and in this respect resemble more the specimen delineated by 

 Kiener.

Hab. Philippine Islands. 



This species, when in fine condition, has the transverse costse prettily 

 marked with small, close-set, olive-brownish dots. These are not 

 mentioned by Reeve or Adams, owing to the fact that the specimens in 

 Cuming's collection which they described are somewhat worn or over- 

 cleaned ; however, they are traceable when closely searched for.

The specimen of this species from the Andamans is rather small, 

 and of a uniform deep brown colour. The three plaits on the colu- 

 mella are whitish, the aperture olivaceous ; and the outer lip has 

 three or four conspicuous tubercular teeth at a short distance from 

 the upper extremity. 



45. Mitra (Cylindra) undtjlosa, Reeve, Conch. Icon, species 

 193, fig. 192. 



Hab. Philippines (Cuming). 



A very short stunted variety was obtained by Capt. Wilmer. It 

 has eight plaits on the columella, whereof the uppermost is much 

 thicker than the rest. 



46. Mitra (Callithea) acupicta, Reeve, Conch. Icon. fig. 76. 

 The Andaman shell agrees precisely in form with the type from 



Zanzibar ; but the longitudinal costse are less numerous.
