ENGINA. 193 



E. CONTRACTA, Reeve. PL 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 figui'e 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. PI. 62, fig. 44. 



Shell white or 3^ellowish, the nodules varying from chestnut 

 to nearl}^ 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 U. 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. albociucta, Pease. 



E. osELMONTA, Duclos. PI. 02, fig. 45. 



Shell longitudinally ribbed ; orange-brown, with darker spots 



forming revolving series. Length, t'5 mill.

orange-brown. Length, 9 mill. 



Habitat unknoicn. 

 E. GiBBOSA, Garrett. PL 62, fig. 47. 



Shell yellowish brown, gibbous in the middle, constricted 

 below ; spire and upper part of body-whorl with distant ribs, 

 whole surface covered by prominent revolving lira? ; aperture 



yellowish within. Length, 8 mill.

I figure this from one of several specimens obligingly furnished
