last whorl is always comparatively higher and more dcscendent. 

 Besides — ami this is to me the most important difference of all — the 

 hairs are placed far more closely together. In the space of 4 s(juare 

 mm. I can count IG hairs on C. erinaceiis, 36 on C. delphax. 



Kohelt gives the dimensions 30 x 23 ; my specimens measure diam. 29, 

 alt. 23-5; diam. 27-5, alt. 21-5; diam. 27, alt. 22 mm.

This species is represented in the neighbourhood of Constantinhafen 

 by two different forms, one nearly typical in size and colouring, the 

 other much smaller, 21x13 mm., the sinuation of the upper lip 

 deeper and almost angular, tlie "beak" at the keel more pointed. I 

 name the latter form var. gcnulahris. 



8. Papuina Kubaryi, n.sp. PL XV. Fig. 4. 



Testa imperforata, sub-globosa, solidula, striis subtilibus transversis 

 et rugulis oblicpic antrorsum decurrentibus sculpta, flavcscens, maculis

 conduentibus picta ; spira convexo-conoidea, sursum violacea, apice, 

 obtusulo nigricante. Anfr. Ah sat convexi, ultiraus tumidus, vix

Forma albina : testa omnino alba, maculis hyalino-translucidis 

 ornata.

In spite of the very different aspect and the entire absence of 

 any keel, I have little doubt that this form is after all an extreme 

 development of P. Tayloriana, Ad. et Rve. The mode of colouration 

 is very similar, also the sculpture, the form of the aperture, with the 

 exception of the "beak," which is less acutely pointed on account of the 

 absence of a keel. At the same time it appears to be quite sufficiently 

 differentiated to claim the rank of a separate species. Mr. Kubary 

 sent me a goodly number of examples, and not a single one shows any 

 transition to the sharp keel of P. Tayloriana, all being rounded at tlie 

 periphery with an almost imperceptible angulation. Pesides, there is 

 half a whorl less, the whorls are more convex, the corrugation 

 somewhat more distinct and coarser. 



The albino form, as mentioned above, is rather frequent. Some 

 examples lack the transparent specks and are uniformly milk-white. 

 There can be no doubt of their belonging to P. Kubaryi, and I believe 

 that P. albocarinata, Smith, ^ stands in the same relation to P. 

 Tayloriayia, as Pilsbry has already hinted.
