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 intermediate carinae on either side are con- 
nected posteriorly and form a \/-shaped 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. trachura, 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, Lifu, Loyalty Is. (Borradaile). 
Genus Odontodactylus, Bigelow. 
1894. Odontodactylus, Bigelow, Proc. U.S. Nat. Mus., XVII, p. 445 (wbi 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
