266 Mr. E. A. Smitli on new Species of Terebridse. 



tudinalibus validis, contiguis, subacutis, leviter arcuatis (in aufr. 

 ultimo circiter 15) instructi, et infra suturam linea impressa 

 spirali inter costas inaequaliter divisi ; anfr. ultimus ad peripheriam 

 zona angusta alba ornatus, inferne fuscus ; columella fusca, leviter 

 contorta. 

 Long. 32 mill., diam. 7. 



Hah. Japan {A. Adams). 



The strong ribs, acute at the edges and contiguous at their 

 bases, and the style of coloration (namely, the upper half of 

 the whorls being white, and the lower portion olive-brown) are 

 the most prominent features of this species. The edges of the 

 ribs are whitish ; and there is a narrow whitish band encircling 

 the periphery of the last whorl, which is of a brown colour 

 towards the base. 



Subgen. Myueella. 



MyureUa fijiensis. 



M. testa subturrita, subulata, poHta, alba, anfractuum medio dilute 

 brunneo obscure zonata ; anfr. planiusculi, costis subvalidis obH- 

 quis paululum arcuatis (in anfr. ultimo 13 sensim ad basim obso- 

 letis) instruct!, et transversim concinue 8- (in anfr. ultimo 16-) 

 sulcati ; cingulum infra suturam inconspicuum ; apertura parva ; 

 columella fere recta ; canalis brevis. 



Long. 21 mill., diam. 4. 



Hob. Ovalau, Fiji Islands. 



The chief characteristics of this species are the regularity 

 of the spiral sulci, about eight in each whorl and double that 

 number in the last, and the obscurity of the infrasutural spiral 

 groove, which is only to be detected in the upper whorls, and 

 consists of a series of elongate punctures between the longitu- 

 dinal ribs. The faint brownish band around the middle of the 

 whorls is probably somewhat faded. 



Myurella turrita. 



M. testa turrita, subulata, polita, albida, dilute fusco sparsim macu- 

 lata ; anfr. planiusculi, ad bases paululum contracti, costis longi- 

 tudinahbus, crassis, aliquando obUquis et arcuatis (in anfr. ultimo 

 19-20 fere ad basim continuis) instructi, suturamque infra inter 

 costas punctorum serie et supra costas sulco minime profundo in- 

 aequaliter divisi, et spiraHter fortiter 4- (in anfr. ultimo 9- ad 10-) 

 sulcati ; apertura brevis ; columella supcrne recta, basi contorta. 



Long. 26 mill., diam. 4|. 



Hah. Torres Straits. 



Perhaps the above may not be the dimensions of a specimen
