382 MOLLUSKS OF THE (JAI^APACOS STEARNS. 



Voii IMartons' <;('ims thus lav described. The National collec^tioii 

 contains, in addition to the above, two examides (Nos. 1l'l'0I4 and 

 102540), collected by Dr. I label several years a^o, presumably at this 

 island, though not delinitely stated. Keibisch reports it from Chatham 

 <Mdy, in the Wolf (collection; three exam])les, abundant on rocks and 

 under stones, with Bid. rnf/uJosus at an elevation of from 300 to 600 

 feet. This species is ''27" of the Eeibisch-AVolf list. His "28" B. 

 {ri('i(rop}/r(/iis) limti, described from two examples, one of these possibly 

 a Junior, is j)r()bably identi(;al with clu'mnit.zioides.

Cliatham Island (Mus. No. 122110). 



Two si)e('iinens were collected at this ishind April 1, 1S88, The 

 National <'olleetion contains two other examples (Mo. 122015), detected 

 by Dr. Simeon llabel, at some one of the ishinds, several years ago, 

 presumably at (Miathani, which is the only island of the gronp where 

 the Fi/y()iis type of bulimoids has been found. The Albatross shells are 

 in perfect condition, the llabel s])ecimens somewhat rubbed. One of 

 the latter is of a pale, dull, reddish tint throughout the greater part of 

 the shell, lighter on the up])er part of the whorls following the suture, 

 with a narrow whitish band on the basal whorl, and the columella white 

 or Avhitish. The other of the llabel examples is white thnmghout; 

 the lower three or four whorls i)receding the basal, are rather faintly 

 banded with pale ferruginous red, which alternate with whitish bands 

 above and below on the basal whorl. The Habel specimens being 

 somewhat rubbed, the ribbing is less conspicuous than in the Albatross 

 examples, and the whitish surface glazing of the Albatross g'pecimens 

 obscures to a. considerable degree tli(> cohn- beneath, as seeu in Dr. 

 1 label's shells. A fuller description than that given by Mr. Dall was 

 published by me in The Xautilus, l)eccnd)er,, 1S92, together with pre- 

 liminary diagnoses of (»ther species from the CJalai)agos and elsewhere. 

 The portion relating to the above is here rei)eated: "Shell slender, 

 elongated, thin, smooth, and shiny, slightly umbilicatcd, with thirteen 

 to. fourteen gradually increasing whorls; whorls slightly convex and 

 longitudinally obtusely i»li»'ated ; suture distinct: aperture ovate and 

 slightly rellccted at the base of the eohunella. Color ashen white, 

 slightly rufous, m ith hints of a narrow reddish band beneath the sur- 

 face glaze.
