CLATHURELLA. 28 7 



C. SCALARIS, Hinds. PI. 16, fig. 78. 



Ribs rounded, but narrower than represented by the figure, 

 running into the suture,.like the lamellae of Scalaria, closely trans- 

 versely striate, whorls convex, with well-impressed sutures; light 

 yellowish brown, with a narrow indistinct chestnut zone below 

 the' middle of the body-whorl. Length, 9 mill. 



Straits of Macassar, coarse sand, 12 fms. (Hinds). 



C. AMABILIS, Hinds. PI. IT, fig. 6. 



Ribs few, distant, narrow, revolving striae fine and close ; pale 

 orange-brown, last whorl with a narrow white band, suture orna- 

 mented with white spots. Length, 16 mill. 



Straits of Malacca, 17 fms., mud (Hinds). 



Very closely allied to the preceding species, but larger, with 

 less numerous ribs. 



C. NEXA, Reeve*. PI. 16, fig. 69. 



Whorls rounded, plicately ribbed, encircled with fine narrow 

 cords, becoming nodulous on crossing the ribs ; lip flattened, 

 sinus broad - whitish, stained with chestnut, the cords darker 

 chestnut or chocolate. Length, 12-15 mill. 



Philippines (Cuming) ; Viti Islands (Garrett). 



C. PHILIPPINENSIS, Reeve. PL 16, fig. 81. 



Tentricose, rather transparent, white, longitudinally ribbed, 

 ribs very delicate, rather compressed, somewhat distant, and 

 variously painted with black or chestnut and opaque-white. 



Length, 14 mill. 



Philippines, under stones, at low-water (Cuming). 



I suspect that this will prove to be a color-variety of the pre- 

 ceding species. 



C. GRANICOSTATA, Reeve. PI. 16, fig. 80 ; PI. 17, fig. 88. 



Yellowish or blush-brown, with a white band above the middle, 

 the nodules darker-colored. Length, 9-13 mill. 



Viti Islands (Garrett) ; Mauritius (Robillard). 

 C. rufinodis, Martens (fig. 88), is a synonym.
