HELIX HEMITROCHUS. 33 



81. At all events, both his form and my darker one are only 

 varieties of H. lucipeta. 



Var. CESTICULUS Gundlach. PI. 20, figs. 65, 66. 



Typically distinguished from H. lucipeta by the stronger striation 

 and generally more depressed form. The coloration varies from 

 uniform whitish or isabella-colored, to deep chestnut or purplish 

 brown, with white subsutural and peripheral zones. The more 

 usual pattern consists of numerous girdles of brown streaks and spots, 

 on a white or yellowish-brown ground. The following description is 

 a translation of Pfeiffer's : 



Very narrowly, almost covered umbilicate, globose-depressed, 

 rather thin, obliquely, densely costulate-striate, scarcely shining, 

 whitish or flesh-tinted, variously painted with undulating or inter- 

 rupted brown bands, rarely nearly unicolored ; spire shortly convex- 

 conoid ; whorls nearly 5, somewhat convex, the last rounded, an- 

 teriorly deflexed ; aperture very oblique, lunate-oval ; peristome 

 pale rose-colored, sub-thickened within, the margins converging, 

 right margin briefly expanded, columellar margin declivous, dilated 

 upward, reflexed. Alt. 71-9 i, diam. maj. 121-17 mill.

 v, p. 348. 



The variations of this form seem to connect H. gilva and H. 

 lucipeta. 



H. PENICILLATA (Gould) Pfr. PI. 32, figs. 50-52. 



Perforate, globose-depressed, rather solid, closely striate, shining, 

 fleshy-white, ornamented with narrow bands of brown dots; spire 

 convex, obtuse ; whorls 4, slightly convex, the last rounded, descend- 

 ing anteriorly ; aperture diagonal, rotund-lunar ; peristome sub- 

 simple, margins subconverging, right lip briefly expanded, columella 

 lip reflexed, flesh-colored. Alt. 9, diam. 15 mill. (Pjeiff&r?),

H. penidllata (GLD. Bost. Journ. N. H. 1842 ?) PFR. in Con- 

 cliyl Cab. p. 422, t. 129, f. 3-5 ; Monogr. iii, p. 226. 



This description and the figures are from Pfeiffer, and may or may 

 not be applicable to the H. penidllata of Gould. Cuban naturalists 

 know nothing definite about the form, and it might be put among 

 the unidentifiable species with advantage. Gould's diagnosis is as 

 follows :
