FUSUS acuminates, 
TAB, CCLXXIV.— Figs. 1, 2, and 3, 
Spec. Char. Elongated, acicular, obscurely cos- 
tated, and longitudinally striated ; volutions 
tumid, with 8 or 10 elevated striae. 
Syn, Murex porrectus. Br cinder, f. 36. 
The costse upon this species, if costae they can be 
called, are very slightly elevated, and very irregular ; 
so much so that some parts of the shell appear entirely 
free from them : it is so much elongated as to be 6 of 
7 times the length of its greatest width. 
FUSUS asper. 
TAB. CCLXXIV. — Figs. 4, 5, 6 3 and 1. 
Spec. Char. Elongated, costated ; volutions tumid; 
costae decussated by 4 or 5 elevated, rather 
acutely knotted, striae or ridges. 
A much shorter shell than the last, and less strongly 
striated lengthwise ; the ridges rise into sharpish ele- 
vations as they cross the costse, which are most remark- 
able on the upper whorls : five times as long as broad. 
This species is generally whiter than the others.
