116 UROCOPTIS OF JAMAICA. 



differ somewhat, the pillar being large in the penult, and next 

 earlier whorls, decidedly smaller in the next preceding (while 

 in the obese form it is most strongly twisted there). 



Var. producta C. B. Ad. Form "much more elongate, sub- 

 conic. A specimen is 1.23 inch long and .34 inch broad" 

 [Ad.]. Known to me by the above note only. It is larger 

 than any form of the species I have seen, measuring about 

 303/4 by 81/2 mm. 



Var. MANCHIONEALENSIS nov. (pi. 29, figs. 35-37). There 

 is also a small form of lata in the collection of the Academy, 

 taken at Manchioneal, in western Portland, by Messrs. W. J. 

 Fox and C. W. Johnson. It measures 17 x 6.3 mm., with 8 

 whorls. The pillar is unusually slender, but noticeably 

 spiral, the curvature greater in the fourth whorl up, as usual. 

 The apex (pi. 32, fig. 82) is smooth, and the early whorls are 

 attenuate. 



Subsp. ISCHNOSTELE nov. PL 30, figs. 53, 54. 



Shell tawny with darker sutural border, in shape like the 

 subcylindric forms of U. lata, from which it differs in being 

 much thinner, with the internal column straight, slender and 

 tapering. Length 24, diam. 8 mm. ; length 22, diam. 7 mm. 

 Special locality not known. 



In this form the pillar resembles that of the typical species 

 of Urocoptis, but in external characters it is identical with 

 lata, so that I dare not separate it specifically. 



2. U. SANGUINEA (Pfeiffer). PL 31, figs. 61-69. 



"Shell rimate, truncate, ovate-cylindrical, solid, glossy, 

 brownish blood-red; suture linear; whorls 10. subequal, a 

 little flat, subarcuately and closely rib-striate, the last whorl 

 not free, obsoletely angular at the base, a little more strongly 

 ribbed anteriorly. Aperture subvertical, orbicular; peri- 

 stome white, scarcely continuous, broadly expanded, shortly 

 reflexed, appressed above. Length 26, diam. 9, width of aper- 

 ture with peristome 7% mm." (Pfr.)
