MELVILL : ADDITIONS TO THE GENUS LATIRUS. 169 



oblong. Ribs stouter than in the fellow species. It likewise has the 

 aspect of a Coralliophila. All the examples I have seen, however, 

 are of uniform shape and size. The mouth is similarly coloured very 

 pale carnation. In my former paper on the genus Latirus' (1891) 

 this was relegated, but erroneously, to the genus Ettgina. My two 

 specimens are both precisely similar, and, as already observed, are of 

 the same alliance as L. corallinus. Indeed, it is possible inter- 

 mediaries may some day be found to occur. A small shell hitherto 

 considered a dwarf variety of L. pulchellns Reeve, may also, with 

 certainty, be placed in the neighbourhood of this group.

This little brightly coloured species, of which the type is unique in 

 the collection of Mr. Ernest R. Sykes, at 'Weymouth, is allied to the 

 much larger Z. turritus Gmel., and craticulatus L. It also may be 

 compared with lautiis Reeve, this, however, being a much more obese 

 species in contour. The colour is bright rufous-ochre, spirally lined, 

 form attenuate-fusiform, solid in substance, whorls 6-7, spirally 

 tornately-lirate, lirse white, unequal, increasing in number on each 

 whorl, till the penultimate possesses six and the body whorl twelve, 

 the interstices are microscopically delicately alveate-decussate, aperture 

 ovate, outer lip thickened, columella twice-plaited, canal short. 

 Long : 12 ; diani. : 5 mm. 



9. Latirus funebris Preston. 

 Latirus fiinebris H. E. Preston, Journ. of Condi., vol. xii., p. 33, fig.

A small fusiform species, dark purplish brown in colour, with 

 closely arranged longitudinal ribs, intersected by spiral grooves, outer 

 lip serrate, columella twice plaited, canal abbreviate. 



Long.: 15; diavi.: 5 mm.
