EnDODONTA MARINA, U. S. 



Shell conoidal, sub-perforated, striated ; colour pale yellowish horn, 

 sometimes faintly banded with chestnut, and tessellated with the same 

 colour on the keel. Spire conoidal, rather obtuse ; whorls 5\, slowly 

 increasing, rather flattened, the last acutely keeled, delicately but rather 

 irregularly striated ; suture margined ; umbilicus covered ; aperture vertical, 

 sub-rhomboidal ; peristome thin ; columella with a large acute plait ; 

 parietal plaits two, one on the penultimate whorl near the outer side, the 

 other on the right lip above the keel. Greatest diameter '13, least "11, 

 height *1 inch. 



Hab. Auckland (T. F. Cheeseman). 



Endodonta neeissa, n. s. 



Shell conoidal, sub-perforated, striated ; colour pale yellowish horny 

 with indistinct bands of chestnut and spots of the same colour on the keel. 

 Spire flatly conoidal, obtuse ; whorls 5^, slowly increasing, rather flattened, 

 the last acutely keeled, delicately and rather distantly striated ; suture 

 margined ; umbilicus covered ; aperture sub-vertical, sub-rhomboidal ; 

 peristome thin ; columella with a large acute plait ; parietal plaits six, two 

 on the penultimate whorl, of which the outer is the larger, one on the right 

 lip above the keel, and three blunt plaits on the basal lip. Greatest 

 diameter -11, least "1, height *07 inch.

Phrixgnathus celia, n. s. H. fatua, Hutton, Trans. N.Z. Inst., xiv., 

 p. 153 (not of Pfeiffer). 



Shell small, depressed, smooth, shining, umbilicated ; colour horny 

 with reddish-brown bands. Spire conoidal, depressed ; whorls 5J, slowly 

 increasing, the last obtusely carinated, faintly striated ; the base delicately 

 spirally striatulated ; suture impressed ; umbilicus narrow, but always well 

 marked ; aperture oblique, sub-rhomboidal ; peristome thin, the colurnel- 

 lar margin slightly reflected. Greatest diameter *15, least *12, height 

 •1 inch. 



Animal with the mantle rather anterior, included ; tail acute, without 

 any mucous gland ; peduncles long, slightly clavate, approximated at their 

 bases. Colour greyish-brown, the anterior portion of the head darker ;

Hab. Dunedin (F. W. H.). 



This species differs from H. fatua in size and colour as well as in being 

 thinner, less conical, and more finely striated. From H. glabriuscula it 

 differs in having the whorls angled ; and from P. conella in the umbilicus 

 being much broader, and the spire more depressed,
