G. 0. Sars (Mediterranean Cumacea, 1878, pp. 5-7, 63, 74, 94, 111, 126, 
& 144) gives some general remarks on this group of Crustacea ^ and 
arranges them as follows : — 
Fam. 1. Cumidce. No natatory branch in the four hinder pairs of 
feet in both sexes ; in the males all segments of the pleon pro- 
vided with two-branched pleopods. Owma, Stephanomma^ Cy- 
claspisj Iphinoe, Cumopsis. 
Fam. 2. Vaunthompsoniidce. A natatory branch (exognath) in the 
three anterior pairs of feet in the females, in all except the last 
in the males ; all segments of the pleon provided with pleopods. 
Vaunthompsonia and Leptocuma. 
Fam. 3. Lampropidcc. A median appendage, telson, at the posterior 
extremity of the body. Lamprops and Platyaspis. ' 
Fam. 4. Leuconidce. Only the two first pairs of segments of the pleon 
provided with pleopods in the males ; maxillae very peculiar ; 
natatory branch of the feet as in the Vaunthompsoniidce. Lexicon 
and Eudorella. 
Fam. 5. Diastxjlidce. Only two pairs of pleopods in the male ; telson 
present ; a natatory branch in two pairs of feet in the females, 
in four pairs of the males. Diastylis and Leptostylis. 
Fam. 6. Pseudocumidce. No spines or teeth on the dorsal shield ; 
only one pair of pleopods in the males ; telson distinct, but very 
short and without spines. Pseudocuma and Petalopus. 
Fam. 7. Campy laspidce. Integument very hard, of scaly or net-like 
structure ; body of the female short, of the male much more 
slender, &c. ; organs of the mouth very peculiar. Only genus, 
Campylaspis (Cuma rubicunda, Lilljeborg).
