Mr. E. A. Smith on a new Species of Helix. 243 



basal margins, narrowly expanded and reflexed, whitish, and 

 margined on the outside with a chestnut band ; the columellar 

 margin white, almost straight, thicker than elsewhere. 



Hab. Hawai, Sandwich Islands. 



This very pretty species closely resembles H. fringiUa of 

 PfeifFer, which inhabits the Admiralty Islands. Indeed it is 

 so nearly related to it, that were I not certain of the correct- 

 ness of the locality whence it was obtained, I should have 

 hesitated to describe it as new. 



It is, however, a thinner, lighter, and smoother shell, the 

 spire is a trifle higher and less obtuse, the whorls a little more 

 convex, more regular, the penultimate proportionally smaller, 

 and the last larger and not showing that decided constriction 

 behind the lip which is so characteristic of Pfeiffer's species. 

 The lip, too, is thinner and without the least trace of a tooth- 

 like projection on the columellar edge. Specimens oi fringiUa 

 in fine condition exhibit distinct spiral strise on the entire 

 surfaces ; such sculpture is only just traceable in young 

 examples of the present species. 



One of these young shells has a particularly beautiful 

 appearance, owing to the broad white band at the periphery, 

 which is margined on both sides by a dark brown stripe, con- 

 trasting prettily with the ground-colour, which is bright 

 fulvous or rich fawn. 



Three specimens, one adult and two immature, have been 

 presented to the British Museum by Mr. H. Glanville Bar- 

 nacle, whose name I feel much pleasure in associating with 

 this species, since to him is owing its discovery. 



This form of HeliXj being so different from any other 

 hitherto found at the Sandwich Islands, led me to think that 

 there must be some mistake with regard to the alleged habitat. 

 I therefore wrote to Mr. Barnacle upon the subject, whose 

 reply runs as follows : — " I am perfectly certain that the spe- 

 cimens I have were grown on the Sandwich Islands, and some 

 of them had the snails in them. Whilst stationed at Kailua 

 I used at times to go shooting at some brackish ponds about 

 8 miles away ; and whilst going quietly amongst the broad 

 reeds to shoot a duck I saw one of the shells about halfway 

 up a reed. I took it and found two or three more that day, 

 and now and then others, but not many. Few Europeans go 

 to these ponds, as it is impossible to find them without a guide 

 over the lava, for there is no road. Some I found with the 

 snail, others without ; those with the animal I put into a cigar- 

 box and filled it up with sea sand j and so the animals died 

 out, and then I washed them."
