New Species of Mollusc of the Genus Helicina. 187 



ebus 5 angustis fusco-pilosis longioribus ornatus, basi impressus ; colu- 

 mella breviter recedens, compressa, alba, callum teuuem, album eraittens; 

 apertura vix obliqua, semicircularis ; perist. tenue, raargine dextro brev- 

 iter reflexo, basali cum columella angulum formante. Opere. ? 



Shell subglobose, thin, pellucid, pale horn colored, with epidermis hav- 

 ing closely set spiral lines of short hairs, beneath the epidermis shining, 

 delicately striate, and with microscopic spiral lines; spire slightly ele- 

 vated, apex rather pointed and tinged with reddish color; whorls 4 

 rather convex, the last rounded and ornamented with five spiral series of 

 longer dark hairs, base impressed ; columella shortly receding, com- 

 pressed, and with thin white callus over the umbilical region ; aperture 

 scarcely oblique, semicircular; perist. thin, the right margin slightly 

 reflected, basal margin forming an angle with the columella. 



Diarn. maj. 9, min. 7, mill. Alt. 5, mill. 



Habitat. Newcastle, in the Parish of St. Andrews, 

 Jamaica, West Indies, at an elevation of about 4,000 feet 

 above the sea. 



Remarks. This interesting species is very unlike any 

 other hitherto found in Jamaica. It has the hirsute char- 

 acter of Alcadia hirsuta C. B. Adams, of that island, and in 

 that respect, as well as in general form has, to a remarkable 

 degree, the aspect of a Schasicheila, without, however, the 

 incised peristome. 



I am indebted for this, as well as many other species, to 

 my valued correspondent Mr. C. P. Grloyne, R. E., who 

 refers to it, the specific name having been communicated by 

 me, in his Notes on the Land Shells of Jamaica, Jour, de 

 Conchyliologie XII, p. 44. January, 1872.
