Lucidella persculpta n. sp. Fig. 1. 



The shell is related to L. lineata, and more especially to L. foxi. 

 It differs from both by its much more depressed shape, smaller size 

 and coarser spiral sculpture, which continues undiminished on the 

 base to the axial callus. Whorls 4^, the last rounded peripherally, 

 impressed around the axial callus. The edge of the well-expanded 

 peristome is slightly scalloped above, but not so strongly as in L. foxi. 

 The tooth within the upper lip is very small, that upon the basal 

 lip strong and squarish, as in L. foxi; but, unlike that species, there 

 is no tooth within the outer margin. 



Fig. 1. — Lucidella persculpta. 



Alt. 1.4, diam. 3 to 3.3 mm.; 4^ whorls. 



Orange Hill and Rose Mount, Montego Bay. Types No. 104,402, 

 A. N. S. P., collected by A. P. Brown, September, 1910. 



The nearest relative of this species is L. foxi Pilsbry, taken by 

 Mr. Wm. J. Fox at a cave near Port Antonio, 4 much further east, 

 on the northern shore. In L. lineata (C. B. Ad.) the spiral sculpture 

 fails near the axial callus, leaving a small smoothish area; the spiral 

 threads are finer, less unequal, and one is generally prominent at 

 the periphery, which is thereby made angular or carinate, as de- 

 scribed by Professor Adams. We consider Mandeville the type 

 locality of L. lineata, as Adams's description applies exactly to the 

 form found there. 5 



Lucidella trochiformis Pilsbry 6 is possibly identical with L. nana 

 Pfr., but if so the radial undulation, producing nodules on the line, 

 was not noticed by Pfeiffer. 



4 So far as we know, this species does not inhabit the "Hotel Fichfild, " as 

 Herr Wagner has it, Conchylien Cabinet, Helicinidce, p. 343. The Tichfield 

 Hotel is at Port Antonio. 



5 We were in error in writing L. nana Pfr. a synonym of L. lineata in these 

 Proceedings for 1910, p. 525. It is a distinct species.
