 " Verwandte Gattungen : Weyprechtia Stuxberg und Amathillopsis Heller." Here for the

The above classification suggests the following comments : — 



The definition of Fam. 2. Dulichidae, Dana, includes the statements, "Das vierte und fiinfte 

 Hinterleibssegmeut mit einander verschmolzen ; von den drei hinteren griffelformigen 

 Spaltbeinpaaren eines fehlend." But in Platophium, Dana, here given as a synonym of 

 Cyrtophium, Dana, the fourth and fifth pleon-segments are not coalesced, and there are third 

 uropods, though small and w ithout rami. 



In Fam. 3. Corophiidae, Dana, Cerapus, Say, is identified with Erichthoiiius, M.-Edw., from 

 which S. I. Smith has shown it to be distinct, and is included in the group which have 

 pairs of rami on the first and second uropods, whereas the .'econd uropods in Cerapus have 

 single rami. Dercothoe, Dana, is probably the female of Erichllumiuif, certainly not the 

 female of Cerapug, Say. Hela, Boeck, being preoccupied, has been changed into Neohela.
