.316 PROCKEDINGS OF THK JIALACOLOGICAL SOCIEir. 



Thymnophora (liminnfa. — Pilsbry, Man. Conch., ser. II, a-oI. ix, p. 58. 



Hah. — Jamaica (C. B. Adams) ; Grenada (Guppy). 



This species was not found by Mr. Smith, and its presence in 

 Grenada rests upon the attestation of Mr. Guppy (Ann. Mag. N. H. 

 18()8, vol. i, p. 436). 



8. Helix (Dentellaria) i'Kupi.exa, Ferussac. 



Helix perplexa, For. — Hist. MolL, vol. i, p. 378, pi. b%a, fi^. 1 ; 

 Pilsbry, Man. Conch., vol. v, p. 89, pi. Ivi, figs. 15-17 ; 

 Keeve, Coneh. Icon., fig. 1210, and figs. 252rt, b, a^^granifera. 



Hah. — " Common in sheltered and shady places, under overhanging 

 roots, logs, etc., below 2,000 feet" (H. H. Smith). 



This " is the commonest of our shells, and is found everywhere " 

 (Lascelles). 



None of the specimens from Grenada have the spiral band on the 

 upper and imder surface so strongly marked as some of the exam])les 

 from Mustiquc, also collected by Mr. Smith. Sir ]lawson llawson has 

 specimens of this species from Martinique, St. Vincent ? , Cariacou, 

 and Baliceaux, the two latter belonging to the Grenadines. 



9. BcLiMULUS (DEyM.3ius) BiNOMiNTS, Smith, nom. nov. PL XXI, 

 Figs. 13, 14. 



JJulimulus indistincUis, Guppy. — Ann. Mag. Xat. Hist. 1868, vol. i, 

 p. 436; Pfeiffer, Mon. Hel., vol. viii, p. 184. 



Hal. — Shady places, 500-1,500 feet, on trees: rather rare. (H. H. 

 Smitli.) 



The specific name indistinctus, haying already been applied to 

 a species of Bidirmdus by Pfeiffer, before its employment by Guppy, 

 it becomes necessary to rename the latter author's species. 



Mr. J. H. Ponsonby possesses a new and interesting colour-variety 

 (var. Lascellesiana) of this species. It is of a very dark, almost black 

 tint, with two narrow yellowish or whitish transverse zones on the 

 peniiltimate whorl, and four on the last. The edge of the peristome 

 is also whitish. The third zone from the suture is the broadest, and 

 the fourth or basal one is sometimes somewhat indistinct. 



It was discovered by Mr. Lascelles, who observes : " It is, I believe, 

 only found on the Annandale estate, and only on one small part of 

 that — a strip of land facing west on a rocky mountain side, at an 

 elevation of 1,000 to 1,200 feet." I have much pleasure in associating 

 this very marked variety with the name of its discoverer. 



The unhanded typical form " is found on this same land, but is not 

 veiy uncommon elsewhere." 



10. BuLiMXJLUS TENUissmtrs (Ferussac). 



Bulhnus tenuissimus (Fer.). — Deshayes, Hist. Nat. Moll., vol. ii (2), 

 p. 72, pi. cxliiJ, fig. 8; Reeve, Conch, Icon., fig. 288; 

 Pfeiffer, Conch.-Cab., ed. 2, p. 241, pi. Ixiii, figs. 25, 26. 



Bulimus Barbademis, Pfeiffer.— P. Z. S. 1852, p. 61 ; Mon. Hel., 

 vol. iii, p. 435. 

 Hab. — " Generally on dry hill-sides, undtn- rotten leaves in shady 



places, below 500 feet; not common." Also, "Windward coast, near 



Lake Antoine ; open place, on herbage and vines " (H. H. S.).
