proportionately longer than in that species. The first five abdominal somites are quite 

 smooth above and their postero-lateral angles are rectangular, but slightly rounded. 

 The sixth abdominal somite bears four pairs of longitudinal carinae, the outermost of 

 which run along the lateral margins and terminate in subacute postero-lateral angles. 

 The carinae of the submedian pair are slightly curved and project a trifle beyond the 

 posterior margin ; between them, in one specimen, there is a short median carina in the 

 posterior part of the somite. The two intermediate7carinae on either side are con- 

 nected posteriorly and form a V- sna P e d figure, and between the innermost of these and 

 the submedians there are several smoothly rounded tubercles. 



The telson is semicircular in outline, about one and a half times as broad as long, 

 and is strongly convex above. It bears a pair of posteriorly convergent submedian 

 carinae, and the surface is otherwise closely covered with smooth rounded tubercles : 

 shortest on the vertex and longest at the edges. The ventral surface is smooth and on 

 the posterior margin (seen from below) three sharp spines may be observed, as well as 

 series of five submedian and intermediate spinules. 



The outer edge of the basal segment of the uropod is strongly arched as in the pre- 

 ceding species, and the process arising from its inferior aspect consists of a single sharp 

 spine bearing a very small tooth high up on its outer margin. The proximal segment of 

 the exopodite is shorter than the ultimate segment and is provided with a series of nine 

 movable spines. The endopod is curved as in C. traduira, but much less distinctly so. 



No secondary sexual distinctions could be detected. 



Only three specimens of Coronida multituberculata are known. Their very small 

 size, 12-13 mm., suggests that they are perhaps immature ; but, with the possible 

 exception of the shape of the rostrum, it does not seem likely that their characters 

 would be much modified by further growth. One male and two females were found at 

 Sandal Bay, Iyifu, Loyalty Is. (Borradaile). 



Genus Odontodactylus, Bigelow. 



1894. Odontodactylus, Bigelow. Proc. U.S. Nat. Mus., XVII, p. 445 (ubi syn.). 

 Carapace little, if at all, narrowed anteriorly ; without carinae ; gastric grooves 

 distinct, cervical groove wholly absent ; antero-lateral angles rounded, cornea of eye 

 not distinctly bilobed. Mandibular palp present and composed of three segments 

 or (?) entirely absent. Ischio-meral articulation of raptorial claw situated at a point 

 in advance of proximal end of merus , the latter segment consequently extending back- 

 wards considerably beyond the joint ; the inferior surface of merus not channelled 

 longitudinally throughout its entire length ; upper margin of propodus not pectinate ; 

 dactylus inflated at base, armed with two to nine teeth on inner margin. 

 Shorter ramus of last three thoracic appendages linear, composed of two segments. 

 Free thoracic and abdominal somites compressed ; distinct carinae present only on 

 last abdominal somite. Telson with sharp median carina and one or more carinae 

 on either side ; strong submedian, intermediate and lateral teeth on distal margin, 

 the first with movable apices ; no submedian denticles (though there may be minute
