 Syu : Am])hilophu8, Stebbing (part). 



Body smooth, and rather robust in foi-m, with comparatively deep 

 coxal plates, the 1st of which, however, are very small, and almost entirely 

 concealed. C'ephalon produced in front to a more or less projecting I'ostrum, 

 liroad at the base. Antennte rather .slender, the inferior ones, as a rnle, 

 somewhat longer than the superior. Mandibles well-developed, with the 

 molar expansion large and pi'otruding, palp .slender, and nearly naked, 

 terminal joint shorter than the penultimate one. First pair of maxillae with 

 the palp not verj' large, and uniarticulate ; 2nd pair with the inner lobe 

 shorter and broader than the outer. Maxillijieds nearly as in the preceding 

 genus, except that the palp is comparatively more elongated and slender. 

 Gnathopoda rather feeble in structure, not very unequal, and scarcely 

 subcheliform, propodos narrow, without any distinctly defined palm, carpus 

 more or less produced at the end interiorly. Pereiopoda of the usual slender 

 form. Uropoda and telson about as in the 3 preceding genera. 



Bemarks. — This genus, established by Boeck, is chiefly distinguished 

 by the palp of the 1st pair of maxillae being uniarticulate, and by the 

 comparatively feeble and not subcheliform gnathopoda. Otherwise it shows 

 a close affinity to the preceding genus ((Titanopsis). It comprises, as yet, 

 3 species, to be described in the sequel.

.Syn : Amphilochus sabrinre, Stebbing. 



Body short and stout, with Ijoldly-curved back. Cephalon scarcely 

 as long as the first 2 segments of mesosome combined, rostrum strongly 

 curved, and reaching nearly to the end of the basal joint of tlie superior 

 antennae, tip somewhat blunted, lateral corners but little projecting, and 

 nearly rectangular. Second pair of coxal plates much smaller than the 

 2 succeeding pairs, and somewhat tapering in their outer part, distal edge 

 narrowly rounded, and exhibiting only 3 small sei'rations in tlie middle ; 4th 

 pair somewhat deeper than the corresponding segment, and finely serrated 

 on the inferior and posterior edges. Last pair of epimeral plates of meta- 

 some somewhat produced at the lateral corners, without however forming 

 any dentiform projection. Eyes of moderate size, rounded oval, with
