208 Rev. T. R. R. Stebbing's Revision of Amphipoda. 



Fam. LencothoidsB. 

 Paealeucothoe, gen. nov. 



First segment of person longer tlian the second. First 

 maxillae with five seta-like spines on the outer plate, the palp 

 very large, but only one-jointed. The maxillipeds have the 

 inner plates broad and long, peculiarly constructed, so as to 

 show two apical margins, one flattened, the other compressed ; 

 the outer ph^tcs, though small, are not rudimentary. The 

 first gnathopods are chelate between the fiftli and sixth joints, 

 the sixth having a truncate apex, grooved for the finger. The 

 second gnatliopods are subchelate, the fifth joint not strongly 

 produced. Telson triangular, oval. 



The tj'pe species is Lcucothoe novce^JioUandice, Haswell. 

 For opportunities of examining this interesting form I have 

 to thank Professor Haswell and the Trustees of the Australian 

 Museum. 



Fam. (EdiceridaB. 

 EXCEDICEROS, gen. nov. 



Distinguished from (Ediceros, Kroyer, by having the 

 rostrum little pronounced, the eyes not contiguous though 

 well developed, the first antennae with a rudiment of an 

 accessory flagellum, the mandibles with well-developed molar 

 and the palp's second and third joints broad ; the first 

 maxillje with numerous setaj fringing the inner plate; the 

 maxillipeds with the inner plates broail ; the gnathoi)0 Is with 

 the fitth joint at least as large as the sixth; the first and 

 second pera^opods without finger and the second uropods not 

 reaching back so far as the first or third. 



The type species is CEdicerus fossor, Stimpson, if, as I 

 suppose, that species is the same as (Ediceros arenicola 

 {?f(Sso7'), Haswell. The latter has been kindly sent me by 

 the Trustees of the Australian Museum. 



Carolobatea, gen. nov. 



Frontal process a])ically subacute, carrying the contiguous 

 eyes. Fourth pair of side-plates much deeper than the rest. 

 First antenna? shorter than the second, flagella in both many- 

 jointed. Lower lip with the inner lobes separate. Mandibles 

 with molar ratlicr weak, second joint of palp slightly curved. 

 Outer j)late of first maxilla3 with nine spines. Second maxillse 

 with inner plate the broader. Maxillipeds with inner plates 

 small and outer plates not nearly reaching apex of the distally
