34 TEREBRA. 



variety of T. strigilata, but has sharp plications and the line of 

 punctures which indicate a sutural space, although no division 

 is defined upon the ribs.

T. HASTATA, Gmelin. PI. 10, fig. 87 ; PI. ^ fig. 86 ; PI. 10, figs. 

 89, 90, 94, 95, 92. 



Elongately cylindrical, somewhat acuminated towards the 

 apex; closely plicated, forming crenulated sutures, the plicae 

 sometimes on the upper part of the whorls only, sometimes 

 covering the whorls to the base; whitish, two- or three-banded 

 with fawn-color to orange-brown, the bands sometimes broken 

 up into large blotches ; the entire surface occasionally uniform 

 orange-brown. Length, 1-1*2 inches. 



West Indies; Wext Africa. 



T. costata, Menke (unfigured) is a synonym ; as is also the 

 West African T. Knockeri, Smith (fig. 86.) 



Yar. ALBULA, Menke. PI. 10, figs. 89, 90, 94, 95. 



Shell narrower in proportion to its length, more subulate, the 

 plications short. 



Australia, Philippines, Straits of Malacca. 



As the specimens usually occur this variety presents sufficient 

 distinctness of form for specific rank, but sometimes the West 

 Indian shells are found exactly like it. Reeve, who does not 

 even make a varietal distinction, includes also the unfigured T. 

 crassula, T. biparlita, and T. incolor of Deshayes, and as he has 

 examined the types, he is probably correct. T. casta, Hinds 

 (fig. 90", and T. mera, Hinds (figs. 94, 95) are synonyms. 



Var. SOLIDA, Deshayes. PL 10, fig. 92. 



The plications are described as only indicated by impressed 

 striae on the last whorl, which is encircled by three translucently 

 yellowish lines. 



Japan. 



Reeve adds that the shell is tessellately enameled throughout 

 with square opaque white blotches on a fawn-cream color surface ; 

 which appears to me to be but an exaggerated way of describing 

 the characteristics exhibited by the figure.
