7. Leptestheria siliqva, G. O. Sars. 

 (PI, in.) 



Of this form, described in my 2nd paper, several 

 specimens, males and females, have since been forwarded 

 1;o me, derived from 3 different localities. Although some 

 slight differences may be found, on comparing the specimens 

 from each locality, I am unable to detect any more essential 

 distinguishing character, and am therefore of opinion that all 

 the specimens in reality belong to one and the same species. 

 It likewise now appears to me beyond doubt, that the 2 

 forms recorded by Baird as Estheria MacguiUivrayi and 

 E. Buhidgei must be adduced to the same species. By the 

 examination of the rich material now at my disposal, I have, 

 indeed, convinced myself that the specimens at first described 

 in my 2nd paper were far from being fully grown, though 

 they evidently had reached to sexual maturity. 1 have also, 

 in the course of the past summer, succeeded in raising some 

 few specimens of this form from a small parcel of dried 

 mud kindly sent to me by Dr. Purcell, and of these, one 

 male specimen lived until late in the autumn, and attained 

 a considerably larger size than those previously examined 

 by me. I have since received from the same gentleman 

 numerous specimens taken by him in the same locality 

 (Green Point Common), but at a somewhat later period of 

 the season. These specimens are of still larger size, and 

 differ also in some other respects from those at first taken, 

 though no doubt can arise as to the specific identity of both 

 forms. In the greater number of the specimens, the shell 

 is covered with a thick crust of argillaceous matter, so
