116 THE VOYACxE OF H.M.S. CHALLENGER. 



this species, iu which the concentric sulci are only beginning to develop. The brown 

 apices to the umbones referred to by him are probably characteristic of this species, as I 

 find them in the specimen before me. 



Sowerby observes that the " inside is orange under tlie umbones and marked with 

 grey near the margin." 



On examining tlie type of his species I find the colour beneath the beaks is 

 scarcely deep enough for orange, but should rather be called gamboge-yellow, and the 

 grey markings near the margin are the exterior zig-zag lines, which are not hidden by 

 an internal w^hite shelly coating as in adult shells. His specimen is said to have been 

 dredged near Sydney, at a depth of 6 fathoms, on a mud Ijottom.

Habitat. — D'Urville Island, New Zealand, on the beach. 



This is a well-known species of a pale whitish-brown colour, and, according to Hutton, 

 common at the Auckland Islands.

Habitat. — Port Jackson, New South Wales, in 2 to 10 fathoms. 



This species is also found at Lake Macquarie, New South Wales, and ofi" the 

 Tasmanian coast. Mr. G. French Angas, who is well known as the author of several 

 papers on the MoUuscan fauna of Australia, liberally presented specimens to the British 

 Museum, from the former locality, and the same institution is indebted to Mr. E. Gunn 

 for others from the latter. The original habitat, " New Zealand," assigned to this species 

 has not yet been confirmed, and it is somewhat doubtful wlictlifv it be correct.
