ate than the outer lip. The white peristome is reflexed. 

 The axis bears two slender, compresssed, subequal lamellae. 

 It is like the Marianao form of U. artemisice in shape, color 

 and sculpture, but differs in the slender axial lamellae, while 

 in artemisice the upper one is stout and cord-like. U. gutier- 

 rezij named for the founder of the Royal Academy of Med- 

 ical, Physical and Natural Sciences of Havana, was discov- 

 ered by Charles Wright, and distributed by him as Cyl. no. 

 370.

Length 11.3, diam. 2.9 mm. ; whorls 10. 



86. U. LIRATA (' Jimeno' Pfr.). 



Shell fusiform-cylindric, rather solid, sculptured with 

 nearly straight, close, cord-like ribs, rufous-corneous. Spire 

 somewhat swollen, rather widely truncate; suture crenulated 

 by the projection of the ends of the riblets. Whorls remain- 

 ing 10, a trifle convex, the last tapering, horizontally pro- 

 duced, more closely costulate anteriorly. Aperture oblique, 

 depressed-circular; peristome white, subequally expanded 

 throughout. Internal column with two compressed, obliquely 

 revolving lamellae, the upper one stronger. Length 13, diam. 

 4% mm., aperture nearly 3 mm. high, a little wider (Pfr.).

Unknown to me. Pfeiffer states that it stands nearest to 

 U. crispula, which also has two parallel lamellae upon the 

 internal column; but in crispula they are equal, less acute, 

 and more obliquely ascending. Moreover, lirata is more 

 swollen, with straighter ribs; the neck longer and projects 

 horizontally forward. Arango queries the locality Matan- 

 zas, but from the characters of the shell, it would be expected 

 to occur in that part of Cuba.
