lines on the scuta are more distinct than in the specimens already referred 

 to. A few specimens differ from both of the varieties already mentioned 

 in having the carina much broader and less acuminate, not barbed, and 

 in having little or no trace of an internal tooth on either scutum. The 

 radiating lines on both scuta and terga are fairly distinct. These speci- 

 mens therefore differ from the typical form of L. anatifera in the absence 

 of the internal tooth on the right-hand scutum and in the shape of the 

 carina. In some respects they seem to come pretty close to L. testudinala 

 Aurivillius, from the Cape of Good Hope. They differ, however, from that 

 species, as described and figured by Gruvel, in the broader carina and 

 in the shape of its fork, and apparently also in having 5 teeth on the 

 mandibles. Neither of these points is of much importance, and but for 

 the absence of the internal tooth on the scutum there is perhaps little to 

 distinguish L. testudinata from L. anatifera. In my Kermadec Island speci- 

 mens both the scuta have the umbonal angle somewhat incurved, but there 

 is nothing that can strictly be called a tooth on either of them. For the 

 present I prefer to look upon these specimens as a variety of the wide- 

 spread and variable L. anatifera. It difEers from L. hillii in having only 

 two filaments. I have numerous specimens from the Chatham Islands that 

 appear to be practically identical with this variety from the Kermadecs. 



L. anatifera is almost cosmopolitan, but has not been recorded from New 

 Zealand seas.

A single specimen washed up on Sunday Island. 



This specimen has the short peduncle completely surrounded by a 

 spherical mass formed of the secretion of the cement-glands, the whole 

 forming a float, as described by Darwin.

, A few specimens from fresh-water swamps, Denham Bay, appear to 

 belong to this species. 



They agree well in shape of the valves with Sars's description and 

 figures. The species is very near to C. viridis Thomson, and, like it, is 

 found both in New Zealand and in Australia.

Spccimcnis from fresh water in swamps at Denham Bay and from under 

 stones in shallow water, Green Lake, agree well with Sars's descriptions.
