Chiton {^Leptocliiton) Sinclair i, Gray: Smith, Voy. "Erebus" and 

 "Terror," Moll., p. 4, t." i, fig. 17. 



The white stripes or spots are not always present ; uniformly 

 brown-black specimens arc often met with. 



Ilab. — North and South Islands of New Zealand, but very local and 

 not common. I am not aware that it has ever been found in Tasmania. 

 Very likely C. peUis-serpentis was taken for this species, since it is 

 not always easy to separate them when the specimens are partly worn. 



23. Chiton canaliculatus, Quoy & Gaimard.

24. Chiton Stangeri, Reeve. 



Chiton Stangeri, Reeve: Conch. Icon. (1847), t. xxii, fig. 150; 

 Hutton, Man. New Zealand Moll., p. 111. 



In size, shape, coloration, and sculpture very much like Chiton 

 limans, but difi'ering in the following points: — The ribs have no acute, 

 elevated grains, but are flattened. The tail valve has very distinct, 

 flatly nodulous ribs. The jugum is less acute, divergence 120°. The 

 imbricating scales of the girdle are very small on both margins, larger 

 in the middle, shining, not mucronated, and very faintly striated, the 

 &tria3 being visible only under strong magnifying power. Length 13, 

 breadth 8 mm. 



This Chiton may be considered to stand in the same relation to 

 Chiton limans as our Ischnochiton longicymhus to /. crispus of Tasmania 

 and Australia. For comparison I had a specimen of Chiton limans 

 from Port Jackson. 



It is evident that this species ranks as very distinct from C. eanali- 

 culatus, with which it has been thought to be identical. 



Ilab. — I found a single specimen of this evidently rare Chiton in 

 Lyttelton Harbour, under a stone at low-water.
