'callosity which is united to the labrum above and being 

 slightly expanded almost conceals the umbilical fissure. 



Length, 7 lines, In-eadth 3i, a smaller specimen is 4f 

 lines long and 2-^ broad. 



The spiral lirations are rather more prominent than the 

 longitudinal ribs, and the three on the superior half of the 

 whorls are finer than those on the lower portion. The 

 points of intersection are faintly nodulous. 



The figure representing this species is not characteristic, 

 for it is taken from a young example, and the form of the 

 mouth is very different from that of the adult shell.

Patella antipodum, sp. n. Tab. \,fi(j. 25. 



Shell rotundately ovate, a little narrowed in front, the 

 apex much inclined anteriorly, placed at a distance of one- 

 fourth of tlie entire length from the front margin, radiately 

 rather finely ribbed, ribs crossed by the fine concentric 

 lines of growth, orange-yellow clouded with white aroimd 

 the middle, varied with ten or eleven black narrow rays 

 placed at nearly equal distances, those in fi-ont being 

 rather more approximated than the rest ; the interior is 

 brilliant pearly orange-yellow, the exterior black rays being 

 visiljle especially at the margin which is finely crenulated. 



Length 28 mill. ; width 22 ; height 9. 



Hab. New Zealand. (Presented by Lieut.-Col. Bolton, 

 R.E.) 



The figure of this species represents the apex decidedly 

 too central. When resting on a fiat surface the anterior 

 and posterior margins only are in contact with it.

Mr. A. Adams describes tlie colour of this species which 

 appears to have been o\-erlooked by Von Martens in his 

 List of New Zealand Shells as " virescenti." All three 

 specimens in the Cumingian collection are yellowish 

 (luteus). He writes "labro intus sulcato," which refers to 

 the three or four shallow sulcations jdaced far within the 

 ajierture. The dimensions of this species are as follows : 

 greatest height 16 mill; diani. 19.
