The latter variety, the type of which is in the British 

 Museum, presented by the Church Missionary Society, 

 differs from the usual form only in being of a more rounded 

 sha])e. Although Zelandica was described seven years 

 previous to ohlonga it is advisable to retain the latter name 

 because the shells to which it is applied are of the common 

 form of the species, and also because the former name has 

 been used already by Quoy and Gaimard for another 

 species, and although this is a synonym of Venus Stutch- 

 biirii. Gray, nevertheless for the foregoing reasons it 

 certainly is preferable to retain the name ohlonga.

As surmised Ijy Von IMartens, List MoUusca New Zeal., 

 p. 4(5, there can be no doubt of the identity of the above 

 two species, for on comparing the actual types, both of 

 which are in the Museum collection, not the slightest 

 difference is traceable. Fig. 3 on pi. 3 aj)pears to represent 

 a species of this genus intermediate between refiexa and 

 V. Siliqua, Desh., which differs chiefly from the former in 

 being of a more elongated form.

The above appears to be but a manuscript name attached 

 to specimens in the British Museum and Cumingian col- 

 lections, and I retain it as certain characters observable in 

 the New Zealand shells may be sufficient to distinguish 

 them from those occurring in South Australia (S. Australis, 

 Lamarck). 



The form of the two species is very similar and the 

 character of the epidermis alike, except that that of 

 Parksonii is rather darker and sometimes marked with 

 interrupted rays of black. But the cliief differences are to 

 be observed within. 



In S. Australis there exists in each valve a single 

 cardinal tooth, or better callosity, broad and spreading at 

 the dorsal margin of the valve and gi-adually thinning as 

 it extends arcuately into it ; behind this callosity towards 

 the anterior end or longer portion of the shell there is a 

 thin rather broadish lobe-like expansion of the ligament 

 placed in a corresponding shallow depression. 



The posterior muscular scar is roundly pear-shaped. 



In S. Parkinsonii the dental callosity is moderately broad 

 and produced acutely towards the shorter or posterior side 

 of the valve and not truncated as in Australis, the exten-
