of 6 whorls, but its characters are so striking that I have not hesitated 

 to found a new species upon it. 



" In general form it considerably resembles C . spniicincta Martens, 

 from east Australia, but it differs considerably in the details of its 

 ornamentation. 



" The genus Cohtmharium, which, as far as at present known, con- 

 sists of a very few species, has not hitherto been recorded from New 

 Zealand. I have associated with this species the name of Mr. Henry 

 Suter, as a mai'k of appreciation of the immense industry displayed 

 in the production of his ' Manual of the New Zealand Mollusca,' pub- 

 lished in 1913. Although it may be necessary to revise the nomen- 

 clature in a considerable number of instances, and occasionally to 

 correct the synonymy, there can be no doubt that this will always remain 

 a standard, or even the standard, work on New Zealand Mollusca. To 

 have produced such a volume, of 1,120 pages, without the advantage of 

 consulting such complete libraries and collections as we have in this 

 country reflects the greatest credit upon the author." 



Siphonalia nodosa (Martyn). 



Trans N.Z. Inst., vol. 47, p. -464. 



Typhis pauperis n. sp. Plate XII, fig. 9, '9a. 



Shell muriciform, small; body-whorl more than half the length of 

 the shell. Apex bluntly acuminate. Protoconch of 2 whorls, the first 

 transparent, the second opaque and tinged with brown, slightly tilted 

 to the right, smooth. Whorls 4, rapidly increasing in size, convex, 

 sharply angled, bearing tubular spines directed slightly backwards and 

 upwards; of these, there are 4 on the last whorl, and 4 smaller, slightly 

 ragged varices terminating in single spines on the angle, which are 

 recurved towards the preceding whorls. Suture well marked. Apei-ture 

 roundly ovate, lips raised and free. Canal slightlj- longer than the 

 aperture, closed, and lightly curved to the right. On the left there are 

 the remains of 3 former canals. Umbilical fissure very narrow. Oper- 

 culum unknown. Colour creamy white, with a faint purplish tinge 

 on the angle of the shoulder, which is lightly polished. Height, 8 mm. ; 

 breadth, 5 mm. ; aperture, 2 mm. ; canal, almost 2 mm. 



Material. — The holotype, from the Poor Knights Islands, 58-60 

 fathoms; and one paratype from near the Hen and Chickens Islands, 

 Hauraki Gulf, 2.5-30 fathoms. The paratype, which is a younger shell 

 with a more narrowly ovate aperture, is in the Dominion Museum, 

 Wellington. 



Remarks. — The only certain previous record of a Recent species of 

 Typhis is Mr. Suter 's, of a specifically indeterminable species from the 

 Great Barrier Island, 110 fathoms. There is, however, a fossil species 

 in the Mount Harris beds, T . hehetatu-$ Button = T . McCoyi Tenison- 

 Woods, for which see Suter, " Revision of Tertiary Mollusca of New 

 Zealand" (N.Z. Geol. Surv. Pal. Bull. No. 3, p. 28), which possesses 

 5 to 6 spines on each varix, and is thus quite distinct from T . pauperis. 

 Of foreign Recent species, T. yatesi Crosse, from South Australia, 

 apparently comes nearest, but this is a stouter and more subquadrangular 

 species. 



In conclusion, I wish to thank Dr. J. A. Thomson for his generous 

 help in the preparation of this paper, and Mr. J. McDonald for pre-
