ACICULINA. 



figured. N. quercina, Marrat, published without figure, locality 

 or dimensions, is stated by Marrat to be " nearly allied to that 

 very variable shell N. corniculum, Olivi, and may be only a 

 variety of it." 

 N. INSCULPTA, Carpenter. PI. 12, fig. 154. 



Shell with close revolving striae, upper whorls of spire slightly 

 costate longitudinally; light yellowish brown, interruptedly 



fasciate or marked with chestnut. Length, '75 inch. 



Oatalina Island, Gal. 40 fathoms. 



I owe to the kindness of Mr. R. E. C. Stearns, the opportunity 

 of illustrating this rare and hitherto unfigured species. 



Subgenus Aciculina, H. and A. Ad. 



The characters " outer lip produced in the middle, variced 

 externally," do not hold good for all the species : in fact, Acini - 

 Una differs from Zeuxis only in the species being longer in pro- 

 portion to their width still, it will be convenient to retain it. 

 X. ANTHRACINA, Garrett. PL 12, fig. 155. 



Smooth, with fine revolving impressed lines. Black or black- 

 ish brown, with a light brown line on the upper part of the body 



whorl ; aperture brown within. Length, 7 mill. 



Viti Men. 

 Only two specimens obtained, of which one (the type figured ) 



is in the Museum of the Philadelphia Academy. Somewhat 

 resembles a Planaxis, but is a true Nassa.

Smooth, pupiforni, slightly costate at the apex, with fine

Philippines, Aracan, Solomon Islands. 



I have unicolored specimens before me, and specimens h;m 

 been collected with from one to three bands. N. Pupinoidr*. 

 Reeve (for N. striata, A. Ad., preoccupied), is a synonym (fig. 

 157).
