290 CLATHURELLA. 
C. PUNCTICINCTA, Reeve. PI. 16, fig. 79. 
Longitudinally rather obscurely plicated, interstices very 
minutely striated, sinus rather large; whitish, with an inter- 
rupted band of chestnut on the periphery, coloring the interstices 
of the ribs so as to form a circle of spots. Length, 8 mill. 
Hab. unknown. 
C. nETUSA, Hinds. PI. 16, fig. 83. 
Ribs rounded, close, forming a coronal on the shoulder-angle, 
crossed by revolving striz ; orange-brown, purplish at the apex. 
Length, 8 mill. 
Straits of Macassar, sand at 8 fms. (Hinds). 
C. eximrA, Reeve. Pl. 11, fig. 5. 
Shell with narrow longitudinal lamelle, fimbriated by the 
intersection of revolving sculpture; sinus rather indistinct, 
canal slightly twisted. Length, 18 mill. 
Philippines, under stones at low-water (Cuming), 
I am not acquainted with this Trophon-like species. The sinus, 
though somewhat indistinct, is fully sufficient, according to 
Reeve, to place it in the Pleurotomide. 
C. SEMIGRANOSA, Reeve. PI. 11, fig. 98. 
Whorls concave round the upper part, nodosely ribbed in the 
middle, granulated beneath; whitish, encircled round the lower 
part with an orange band. Length, 8 mill. 
Hab. unknown. 
C. CAVERNOSA, Reeve. Pl. 17, fig. 10; Pl. 19, fig. 69. 
Slightly angulated above, longitudinally distantly ribbed, 
latticed with narrow raised revolving ridges, cavernously grooved 
near the base; chestnut, lighter on the ridges. 
Length, 6-7 mill. 
Philippines (Cuming); Viti Is. (Garrett). 
C. infrasulcata, Garrett (Pl. 19, f. 69), is a synonym: the 
figure does not represent the type specimen nearly as well as 
does that of Reeve. 
C. mIcAns, Hinds. PI. 17, fig. 8. 
Chestnut-color, with small, rather sharp, whitish, oblique ribs, 
fading towaras the suture; back of last whorl smooth; lip thin, 
acute, smooth within. Length, 8 mill. 
Gulf of Papagayo, mud at 14 fms. (Hinds).
