74 HELIX-PAPUIXA. 



obsoletely keeled or angulated near the upper end of the lip, the 

 keel vanishing altogether on the last half of the whorl ; whorls 4*, a 

 little convex, having no other sculpture than the arcuate lines of 

 growth (except in young shells, where they are obsoletely spirally 

 striated), the last somewhat ventricose, very shortly deflexed at the 

 aperture ; beneath paler or horn color and a little concave in the 

 middle or umbilical region ; the aperture is very oblique, very irreg- 

 ularly triangular lunate, white within banded with black and brown 

 (the 'latter not visible exteriorly); lip not much thickened on the 

 outer and basal margins, narrowly expanded and reflected, whitish, 

 and margined on the outside with a chestnut band ; the columellar 

 margin white, almost straight, thicker than elsewhere. (Smith.) 

 Alt. 15, greater diam. 24, lesser 21 mill.

This very pretty species closely resembles H.fringilla of Pfeiffer, 

 which inhabits the Admiralty Islands. Indeed it is so nearly related 

 to it that were I not certain of the correctness 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 with- 

 out the least trace of a tooth-like projection on the columellar edge. 

 Specimens offringilla in fine condition exhibit distinct spiral stride 

 on the entire surface ; 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 contrasting prettily with the 

 ground color, which is bright fulvous or rich faun. 



Three specimens, one adult and two immature, have been presented 

 to the British Museum bv Mr. H. A. Glanville Barnacle, whose

name I feel much pleasure in associating with this species, since to 

 him is owing its discovery. 



This form of Helix, being so different from any other hitherto 

 found in the Sandwich Islands led me to think that there must be 

 some mistiikc with regard to the alleged habitat. I therefore, wrote
