1878.] FROM THE ANDAMAN ISLANDS. 813 



39. Latirus incarnatus (Deshayes), var. 



Turbinella incarnatus, Desk., Kiener, Coq. Viv. pi. 18. fig. 3; 

 Reeve, Conch. Icon. iv. fig. 55. 



Hab. Philippines; Australia. 



The shell from the Andaman Islands, which I consider a variety of 

 this species, is light brown and darker between the ribs ; the apex of 

 the spire is pinkish ; and the body-whorl has two spiral whitish or 

 yellowish lirse, one above and the other below the middle of it, the 

 former being visible on the penultimate and antepenultimate whorls. 

 The aperture and columella are pinkish, the outer lip finely lirate 

 within ; and the columella has one or two rather indistinct plicae at 

 the base. 



40. Mitra mcesta, Reeve, Conch. Icon. ii. sp. 323. (Plate L. 

 fig. 13.) 



Hab. Philippine Islands. 



Shell fusiform, turreted, olive-brown, subrimate. Whorls 10 or 11, 

 shortly tabulated above, but very slightly convex at the sides, spirally 

 grooved with three narrow subequidistant sulci, the uppermost one 

 at the top of the whorls, dividing off a thickened edge to the tabula- 

 tion, which is channelled ; this thickened belt is of a brighter brown 

 colour than the rest of the shell. Last whorl transversely sulcated 

 throughout; sulci about 11 in number; a few of the superior ones, 

 with the exception of the^ uppermost, more or less obsolete; those 

 below the middle broader and deeper, leaving raised ridges or lirse 

 between them. Aperture narrow, brownish within, a little less in 

 length than half the entire shell ; columella furnished with a thickish 

 callosity, with a raised free edge forming in the umbilical region a 

 slight fissure ; plaits 4, the uppermost thickest, the others in turn 

 by degrees finer; basal channel and tip of the whorl dark brown. 

 Length 19 mill., diam. 6g. 



This species is remarkable on account of the turreted character of 

 the spire. The tabulation of the whorls, however, is narrow and 

 shallowly channelled. The Andaman specimen differs from the 

 type in having the whorls more distinctly turreted ; the spiral sulci 

 are not so pronounced ; and the colour is somewhat different. In the 

 type (which is a worn shell), the upper part of the whorls is white, 

 whilst in the specimen above described it is light brown.

Hab. Eastern Seas. 



In describing this species Adams writes, " labro intus sulcato." 

 I have carefully examined the type specimens in Cuming's collection 

 and also the Andamese shell, and do not find a trace of sulcatum 

 within the labrum of any of them, and therefore conclude that the 

 observation of Mr. Adams was incorrect. 



The body-whorl has two broad purplish-brown bands indistinctly 

 separated by a faint light zone occupying the greater part of the whorl. 

 Beneath the suture there is a greyish-white band. The entire surface
