serted are sprinkled with minute red-brown points; the anal 
siphon is conically pointed, and protrudes the usual hyaline 
tubular valve ; the branchial is truncate. The branchiz are 
narrow, elongated, pale brown, and composed of only one 
lamina, on each side, which have all the incidents of that 
organ in A. phaseolina, to which we refer; but there are two_ 
distinct palpi, that are long, narrow triangular, pointed, pecti- 
nated within, and less so on the outer surface, of a similar 
colour as the branchie. We believe that most of these 
animals emit byssal filaments. These notes show that this 
species is in close accordance with its congeners; the testa- 
ceous subtriangular ossicle of the hinge emphatically pro- 
nounces it a member of the Anatine. The lustrous aspect of 
the interior of the valves has been considered of greater im- 
portance than it deserves; that character may indicate an 
affinity with Pandora, but, as far as regards generic consi- 
derations, is of little value. Nothing can outweigh the cha- 
racters of the ossicle and smgle compound branchial lamina 
on each side the body; these indelibly mark the position of 
the present species. 
This very elegant object is often taken im the coral zone at 
Exmouth. In empty shells the ossicle is absent ; but we have 
at certain seasons captured many live specimens. The sandy 
coat with which the shell is clothed for the protection of the 
animal must be removed before all its beauty can be seen.

We have no hesitation in relieving the British list from the 
genus Neera; indeed we have no choice, as its only species is 
a strict Anatina — the Thracia of the moderns — haying the 
crescent-shaped, or in this case, the double paralleled sub-
