HELIX-PAPUINA. 75 



to Mr. Barnacle upon the subject, whose reply runs as follows : " I 

 am perfectly certain that the specimens 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 eight miles away ; and whilst going quietly amongst the 

 broad reeds to shoot a duck I saw one of the shells about half way 

 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 ; and so the animal died out, and then I washed them." 



This circumstantial account removes all doubt respecting the true 

 home of this shell. Notwithstanding its close affinity to H. fringilla, 

 the remoteness of the habitats of the two species and the extreme 

 isolation of the Sandwich Islands are sufficient reasons in themselves 

 to determine the specific distinctness of these shells. (Smith.) 



(13) GROUP OF H. HELICINOIDES. 



Imperforate, trochiform species, with rhombic aperture, the lip 

 thickened within, not expanded, or only slightly ; the columellar Up 

 not expanded or reflexed. 



These characters define one of the most distinct groups of Papuina, 

 a group far more deserving of a sectional name than H. fringilla, 

 H. antrorsa or other of the species representing so-called " sections." 



I have examined many specimens of all the species except H. 

 zelina, H. cyrene and H. quirosi. 



The species inhabit the Admiralty Is., Solomons and New 

 Hebrides. 



In all other groups of Papuina the columellar lip is reflexed. 



H. LABILLARDIEREI Smith. PI. 15, figs. 91, 92, 93. 



Imperforate, trochiform, spire conical, the periphery of the last whorl 

 acutely keeled in front, keel more or less obsolete on the latter 

 portion. Surface lusterless, having rather coarse and irregular 

 oblique striae. Color whitish unicolored, or with a broad suffused 

 brownish band below the middle of the body-whorl, or entirely light 

 pinkish-brown ; the apex black. Whorls 5 ; base very convex, deeply 

 impressed in the center.
