SUTER : ON NEW LAND-SHELLS FROM NEW ZEALAND. 157 



Aperture vertical, lunate. Outer lip regularly arched, sharp, the 

 inner lip arcuate, very little thickened, and not reflexed. Umbilicus 

 broad, perspective, showing all the whorls, in width about 1-2 mm., 

 or somewhat less than one-third of the greater diameter of the shell. 

 Diam. maj. 3-2, min. 29 mm. ; height 1*4 mm. 



Type in my collection. 



Hah. — In native bush, Waitakerei Range, about 6 miles from 

 Henderson, Province of Auckland (H. S.). 



Unless closely examined this species may easily be taken for 

 E. anguiculus or E. corniculum, subsp. maculata, but it can at once 

 be separated fi'om both of them by the spiral threads on the base. 



Laoma (Phrixgnathus) Moellendorffi, Suter. 

 Exemplum sin is trorsum . 



The occun'ence of a normally sinistral species of this genus in 

 Tasmania, Laoma Weldii, T. -Woods, is a well-known fact, but from 

 New Zealand up to this time no sinistral Laoma has been known ; my 

 surprise, therefore, was great indeed when, in January last, I found 

 a beautifully developed sinistral specimen of L. Moellendorffi,. The 

 shell has all the characters of the species described by me in 1896, 

 except that it is sinistral, the incremental strias much more oblique, 

 the circumference slightly oval, and the last whorl descending ; it is 

 also somewhat larger, the greater diameter being 3"25 mm., though 

 there are only four whorls, as in the type. 



Type in my collection. 



Hah. — In native bush near Cowes Bay, Waiheke Island, Hauraki 

 Gulf (H. S.). 



Realia turriculata, Pfr., n. subsp. lepida. 



A most graceful small variety, of a much lighter colour and smaller 

 dimensions than the typical form. The chestnut zigzag bands are 

 narrower and less numerous, the spire is more elongate and more 

 acute, not convex, but straight; the whorls, 7^-8 in number, are 

 more convex, and the suture is deeper. Diam. 4, height 7*5 mm. 



Extreme specimens vary from 3 X 6'/> to 4 x 8 mm. 



R. turriculata (specimens in my collection) varies from 4 X 8'5 

 to 5 X 11 mm. 



Type in my collection. 



Llah. — Forty Mile Bush, North Island (H. S.). More plentiful on 

 limestone formation. 



In the same locality also occurs an albino form (mut. alhina), in 

 which the shell is of a cream tint and the zigzag markings devoid of 

 colour, being light horny and pellucid.
