152 Dr. J. 0. Melvill on Marine Mollusca 



whole surface of the two lower whorls is closely spirally 

 Urate. Allied to L. rosea, Pilsbiy, from Japan, but smaller. 



Exclusive of this new species, five others of this genus 

 have, so far, been reported from this region, viz. : — 



1. L. fiU/era, Desh. 



This needs further investigation. I cannot find any 

 specimens in the collection so named, as I understand, by the 

 late Mr. E. A. Smith. 



2. L. Iceta, Montr. =costulosa, G. B. Sowb. 



In three or four dredgings in Gulf of Oman. 



A very prettily painted shell, depresso-diseoid in form, 

 spirally closelv Urate, variegated with rose-coloured spots 

 radiating round the surface. Also a New Caledonian species. 



3. L. munda (H.Adams) COLLONIA ; Sowerby, Thes. 



Conch., Turbo, pi. xiii. fig. 163. 



Persian Gulf. 

 Very minute. 



4. />. pilula, Danker. 



Maskat (Muscat) and Charbar, 5-6 fathoms. Also Bahrein, 

 and in two or three soundings, Gulf of Oman. 



A heavily built little round shell, with shouldered whorls, 

 and buff or cinereous spiral spotting and blotches on a dull 

 white ground. Umbilicus margin coarsely crcnulate. 



5. L. rubens, Melv. & Stand. 



Persian Gulf, Mussandam, 30 fathoms ; live examples. 

 Also at 60 and 15(5 fathoms in the Gulf of Oman. 



A somewhat smooth, angled species, shining, reddish in 

 colour, very abundant at 156 fathoms, rarer at a less depth. 



Others verv possibly occur. The species are hard to 

 discriminate, and may vary more in sculpture and colouring 

 than is supposed to be the case. 



The genus is mostly Eastern, but several striking species 

 occur in the Sandwich Isles and western coasts of America.
