CLATHURELLA. 283 



C. oxYCLATHRUS, Martens. PL 16, fig. 49. 



Whorls clathrate by distant longitudinal and revolving lirae, 

 forming nodes at the intersections, interstices finely cancellate ; 

 sinus narrow and deep; light yellowish brown. 



Length, 1 inch. 



New Guinea. 

 C. CUMINGII, Powis. PI. 26, fig. 76 ; PL 23, fig. 90. 



Ribs slightly nodulous, columella spirally plaited, canal very 

 short and slightly recurved ; lip somewhat thin, without external 

 varix, sinus small, distinct ; pale orange-brown with small deeper- 

 colored spots, the revolving striae white. Length, 34 mill. 



Grimwood's Island ; Philippines. 



C. albibalteata, Reeve (PL 23, f. 90), appears to be a slight 

 variation only in coloring and sculpture from the type. 



C. TRITONOIDES, Reeve. PL 23, fig. 91. 



Delicately cancellated with very finely nodulous longitudinal 

 ribs and elevated transverse striae ; lip thickened, sinus small ; 

 yellowish brown, obscurely banded with white in the middle. 



Length, 23 mill. 



Philippines (C tuning). 



C. FENESTRATA, ReCVC. PL 26, fig. 83. 



Shell thin, pellucid, whorls latticed throughout with rather 

 distant superficial ridges, lip simple, sinus rather broad ; trans- 

 parent white, faintly stained with orange. Length, 10 mill. 



Philippines, coral sand at 9 fms. (Cuming). 



The Messrs. Adams place this in Daphnella on account of its 

 thin lip, a feature which I suppose to be due to juvenility, as the 

 shell has the facies of a Clathurella. 



C. OCTANGULA, Dunker. PL 16, fig. 50. 



Shell solid, obtusely shouldered, strongly ribbed, transversely 

 sutistriate ; yellowish white, with an interrupted chestnut band. 



Length, 10 mill. 

 C. SINCLAIRI, E. A. Smith. PL 34, fig. 91. Japan. 



Spiral striae close, most apparent in the interstices of the ribs ; 

 pale brown or purplish brown, with a central pale spiral band. 



Length, 11 mill. 



New Zealand.
