ENGINA. 191 



E. SATORIDA, Duclos. PL 61, fig. 27. 



Ribs rather distant, prominent, well-rounded ; dark chestnut, 



with numerous narrow, nearly black revolving lines. 



Length, 5 mill. 



Habitat tmknown. 

 E. NUMiciA, Duclos. PI. 62, fig. 28. 



Yellowish brown, with three chocolate bands. Length, 6 mill. 

 E. Reevei, Tryon. PI. 62, fig. 29. 



Yellowish white, ribs marked with chocolate, forming inter- 

 rupted revolving bands. Length, 16 mill. 



Panama to Cape St. Lucas, L. Cal., Australia (Brazier). 



Figured b}^ Reeve as Ricinula alveolata, Kiener — a very dif- 

 ferent species. The Australian habitat is given upon the 

 authority of an excellent conchologist. 



E. BELLA, Reeve. PI. 62, figs. 30-32. 



Spire conically acuminate, base of aperture contracted, elon- 

 gated and recurved; roseate, with two broad chestnut bands, 

 within which the tubercles are lighter. Length, 20 mill. 

 Philipinnes (Cummg); Polynesia (Pease); 



Lord Hood^s Isl. (Cuming); Solomon'' s Is. (Brazier). 



I include in the synonymy E. recurva, Reeve (tig. 31), and 

 U. fragaria, Wood (fig. 32). I have alread}^ described and 

 figured this species as a Peristernia (vol. iii, 82), but reproduce 

 it here, as the generic characters are not very strongly marked, 

 and some good conchologists prefer to consider it an Engina. 



E. PULCHRA, Reeve. PI. 62, fig. 33. 



Shell gibbous, angularly shouldered, strongly ribbed, crossed 

 by revolving riblets ; violet-brown, with a light central band. 



Length, 15-18 mill. Panama, Galapagos Is. 



It is E. Reeveana, C. B. Ad. Mr. Pease writes : * " I have 

 received from Dr. P. P. Carpenter a specimen from the Gala- 

 pagos Islands, labeled 'Type of (Sistrum) ochrostoma^^ and also 

 one from Cape St. Lucas, described by him as '■ ochrostoraa, var. 

 rufonotata.'' They differ widely from the Polynesian ochro- 

 stoma, Blainv., belonging to another genus — Engina. The type 

 agrees with the description of Buccinum jyulchrum, Reeve, col- 

 lected by Cuming at the Galapagos Is."
