L. similis T. and A. Scott, 1913, p. 202, pi. 61, figs. 5 and 6, has no 

 dorsal carapace, no free thorax segment, and the posterior processes 

 are dorsal. These facts with other details warrant its transfer to the 

 new genus Lernaeopodina. 



L. spinads Brian, 1912, p. 36, pi. 5, fig. 8; pi. 11, figs. 3 to 6, shows 

 in the male a structure entirely distinct from Lernaeopoda and is 

 accordingly transferred to the new genus LerTiaeopodina. 



L. stellata Blainville, 1823, p. 112, was figured by Milne Edwards, 

 1840, pi. 40, fig. 12, but has never been well enough described to be 

 located anywhere definitely.

LERNAEOPODA BRONGNIARTU Blainville. 

 Lemaeopoda brongniartii Blainville, 1822, p. 442, figs. 15 and 15a. 



Generic characters of female. — Smce this was Blainville's type 

 species, and since it has l3een seen by no other observer, it seems best 

 to translate Blainville's original description, explainmg m paren- 

 theses the appendages and parts designated: 



Body slender, quite elongate, divided into an oval abdomen (trunk) and a cepha- 

 lothorax, flattened and covered with a hard carapace; a pair of palps (first maxillae), 

 short, stout, conical, and subarticulate, accompany the mouth; two pairs of legs (second 

 maxillae and maxillipeds), articulated and furnished mth claws, on the thorax; egg 

 sacks short and subcylindrical. The anterior pair of legs (maxillipeds) short and 

 formed of two joints and one claw; the po.sterior pair (second maxillae) much the longer, 

 slender, cylindrical, with a terminal flattened, triangular claw 



The abdomen (trunk) is oval and a little flattened. The two sacks with which it 

 terminates behind are covered with a horny skin, somewhat transparent, which per- 

 mita one to see that their interior is filled with a hepatic substance, fully resembling 

 that in the abdomen. The long legs (second maxillae) were made up in the same way. 



To this may be added that the cephalothorax is inclmed to the 

 tnmk while the posterior processes, or sacks, as Blainville calls them,
