dently assert that it does not exist there. So you see there is no es- 

 cape from the deduction that Cook's people took it at the He Amere." 



P. ALEXANDER var. PATULUS Kobclt. Page 35. 



Differs from the type by the spreading aperture, obsolete parietal 

 tooth, black-brown epidermis zoned with black, dull buff color of the 

 aperture and orange throat. Alt. 100, diam. maj. 62, min. 43, ob- 

 lique length of aperture 62 mill. Neighborhood of Kanala. (Kobelt, 

 Conchyl. Cab., p. 115, pi. 28, f. 1.) 



P. PORPHYROSTOMDS var. UMBILICATUS Kobelt. 



Widely but half-covered perforate ; thick and ponderous; the lip 

 much thickened, white. Alt. 81, diam. 37, aperture with peristome 

 40 mill. Govuro, on the west coast of New Caledonia (Layard 

 coll.). Kobelt states that this variety represents an abnormal condi- 

 tion become constant. (See Conchyl. Cab., p. 119, pi. 29, f. 5, 6.)

Since the account of this species was printed, I have received from 

 Dr. J. C. Cox a magnificent specimen retaining the cuticle on all but 

 the earlier whorls. It is green, the last whorl streaked with darker, 

 and with a whitish border along the suture; the penultimate whorl 

 becoming yellowish-green with oblong olive spots, as in P. sanchris- 

 tovalensis. Above this the cuticle is absent, and the color a lively 

 pink. The aperture is flesh-colored within, lip reddish-brown ; the 

 columellar fold being nearly white. The spiral corrugation is well 

 developed. 



This specimen confirms the close relationship claimed to exist be- 

 tween cleryi and sanchrittovalensis (p. 98).

 fig. 6. 



A decollate and 'nearly white example was figured on plate 38. 

 The specimen now shown, which I owe to the liberality of Dr. Cox, 

 is decidedly yellow, has 5 whorls, of which H are punctate, and tiie 

 base is but slightly saccate. Alt. 54, diam. 23^, aperture 34 mill.

A specimen received from Dr. Cox is slightly stouter than Kobelt's 

 figures. It has a thin pale buff cuticle indistinctly mottled with
