SUTER : COMMUNICATIONS FROM NEW ZEALAND. 53 



4.— Endodonta (Ptyehodon) upeweraensis, n. sp. 



(Plate iii, figs. 7 — 10.) 



Shell minute, depressed globose, perforated, irregularly and zigzag 

 banded with rufous on a yellowish-white ground, closely-ribbed, about 

 15 riblets per mill.; spire low conical. Whorls 5^, flatly rounded, 

 periphery regularly convex; the volutions first slowly, then a little 

 more rapidly increasing, protoconch smooth, consisting of i|^ whorls, 

 suture impressed. Aperture subvertical, lunate, peristome straight, 

 acute, margins distant. Mouth with 11 lamellae, two on the penulti- 

 mate whorl, a high, rather stout and long lamella below the middle, 

 and a second threadlike lamella half way between the first and the 

 upper margin, far back in the aperture in adult specimens, but easily 

 visible in young shells, not shown in the figures ; a third lamella on 

 the very slowly descending columellar lip, forming a long, sharply 

 pointed tooth ; on the parietal wall there are eight long, narrow, sub- 

 equidistant threadlike folds. Base conve.x, perforation minute, open, 

 no reflection of the columellar lip. 



Diam. maj. 2"8, min. 2"6; height i"5 mm. 



Hah. — Ngaputahi, Urewera Country, New Zealand, where it was 

 found by Mr. A. Hamilton of Dunedin, to whom I am indebted for 

 so many new forms of New Zealand mollusca. Type in my collection. 



This species may at once be distinguished from all the other 

 species of Ptyehodon by the character and situation of the lamellae ; 

 it is the eighth species of that subgenus. 



5.— Lagroehilus lig-narius (Pfr,). 



It is about one year since I was favoured with the rare opportunity 

 of examining the living animal of the above species, when I was able 

 to state that there is a very distinct notch visible on the upper surface 

 of the tail, just behind the operculum. This being characteristic of 

 the genus it confirms Dr. von Mollendorff's opinion on the generic 

 position of this and allied species. Well preserved specimens of the 

 shell show longitudinal, membranaceous plaits, which however are 

 very easily rubbed off. 



6.— On Clessin's New Species of Sealaria from New Zealand. 



Having ascertained from lYiQ '■'■ Zoological Record" for 1897 that 

 Clessin had described several new species of Scalaria from New 

 Zealand, I requested Mr. E. R. Sykes to send me copies of the diag- 

 noses and tracings of the figures, and I am very grateful to him for 

 having so kindly attended to my wishes, and I am now in a position 

 to give my opinion on Clessin's new species.
