The sculpture is variable ; in some specimens the longitudinal 

 ribs are well developed, iu others these are subordinated to the 

 close revolving striae I unite with this species T. tessellatus^ 

 Reeve (fig. 145), the coloring and sculpture of which are not per- 

 manently distinctive. 



T. ANGULATUS, Reeve. PI. 15, figs. 146, 141- 



Yellowish white, sometimes with narrow brown bands. 



Length, '5 inch. 



FJiiUppiin's, vinder stones at low water. 



There is nothing but the slight shoulder on the whorls to dis- 

 tinguish this from T. concinnus. 



T. FiCTiLis, Hinds. PI. 15, fig. 150. 



Varices three, whorls longitudinally, obliquely ribbed, and 

 transversely finely striated. Brown. Smooth within the small 

 ai)erture. Length, -75 inch. 



UAgulhas bank, Cape of .Good Hope, 50 to 60 fathoms. — Hinds. 



I am not acquainted with this species. 



T. picTUS, Reeve. PI. 15, fig 154. 



No varices. Ijongitudinally very closel^^ ribl^ed, transversely 



elevately striated. Tessellated with reddish brown. 



Length, -7 inch. 



GalapagoH h., under stones at low water. 



I do not know this species, but the figure is singularly like a 

 narrow form of Cohtmhella varia, Sowerby. 



T. CREiuiisTRiATUS, Carpenter. 



Shell like T. jncius, Reeve, but closely spirally striate ; white, 

 densely maculated with reddish chestnut ; aperture scarcely 

 varicose, simple within. Length, "58 inch. 



Bay of Panama. 



Is destitute of the expressed spiral rilts of T. pictus. The 

 only specimen seen has no teeth in the aperture. It may ])e only 

 on the verge of maturity, or it may belong to a Buccinoid genus. 



The above is a copy of the original description — which is 

 worthless, as very probably is also the species. It may not 

 really ditlcr from 2\ jncius, or it may well be a young Columbella 

 varia.
