ENGINA. 193 



E. CONTRACTA, Reeve. PI. 62, figs. 41, 42. 



Shell yellowish brown, interior of aperture white or rosy, teeth 

 white. Length, 13-18 mill. 



Panama and 8t. Elena, W. Columbia, under stones (Cuming). 



I do not find any good distinctive characters in the figure of 

 E. acuminata, Reeve (fig. 42). 



E. EXIMIA, Reeve. PI. 62, fig. 43. 



Shell fusiform, spire acuminated, whorls rounded, concentri- 

 cally finely ribbed, elegantly cancellated with delicate ridges ; 

 yellowish white, ridges brown in zones between the ribs. 



Length, 22 mill. 



Manilla, in coarse sand at 6 fathoms (Cuming). 



The pertinence of this species to Engina may well be doubted. 



E. FUSIFORMIS, Pease. PL 62, fig. 44. 



Shell white or yellowish, the nodules varying from chestnut 

 to nearly black, with a central white band, and sometimes others 

 at the suture and towards the base ; occasionally the tubercles 

 near the base are irregularly variegated black and white ; lips of 

 aperture dark-colored. Length, 15-18 mill. 



Rowland IsL, Viti Isles. 



It is a narrower form than E. alveolata, Kiener,but is possibly 

 only a variety of that species. I have before me specimens with 

 the nodules chestnut-colored and a central white band which I 

 suppose to be identical with the unfigured E. albocincta, Pease. 



E. OSELMONTA, Duclos. PL 6% fig. 45. 



Shell longitudinally ribbed ; orange-brown, with darker spots 

 forming revolving series. Length, 7 '5 mill.

 E. AURANTIA, Duclos. PL 62, fig. 46. 



Surface of shell decussated into close, prominent tubercles ; 

 orange-brown. Length, 9 mill. 



Habitat unknown. 

 E. GIBBOSA, Garrett. PL 62, fig. 41. 



Shell yellowish brown, gibbous in the middle, constricted 

 below ; spire and upper part of bod} T -whorl with distant ribs, 

 whole surface covered by prominent revolving line ; aperture 

 yellowish within. Length, 8 mill.

I figure this from one of several specimens obligingly furnished
