G54 ON CRUSTACEA BROUGHT BY DR WILLEY FROM THE SOUTH SEAS. 



its quadrate apical part, in which the sides are parallel, the distal margin a little 

 convex. The uropods (seen from below) are as broad as long, the much narrowed 

 distal part not closely filling the space between the terminal segment and its pre- 

 decessor; the inner rami reach the end of the terminal segment, their apical setules 

 being visible beyond it ; the conical outer rami reach the end of their own peduncle. 



Colour mottled with brown and yellowish markings of an ordinary type. Length, 

 11—12 mm. 



Habitat. Lifu, Lo}-alty Islands. Budde-Lund's Armadillo nignnus, of unknown 

 habitat, probably from the Cape of Good Hope, seems to approach this species nearly, 

 but it is described as very minutely grauular, with the ordinary tuberculosities 

 manifest on both sides of the bod\- : with 20 or more ocelli to the rather large eyes, 

 the terminal segment of the pleon scarcely broader than long, its rectangular apex 

 longer than broad, slightly carinate longitudinally ; the peduncle of the uropods much 

 longer than broad, the colour grey, or grey-black, with paler sides. The side-plates 

 of the (first) segment of the peraeon are said to be entire, thin. 



CUBARIS DOLLFCSr, n. sp. 



Plate LXX b. 



This species makes the nearest approach to C. simplex (Dollfus), 1895, from North 

 Madagascar, but is distinguished from it by the longer rami of the uropods, and as 

 well by the anterior margin of the prosepistome as the apical of the caudal segment, 

 both of which are straight in the species compared. 



The present species has the body only moderately convex, minutelj' squamose. 

 The prosepistome is well in advance of the front, broadly convex in the middle, 

 with subacute lateral lobes. Eyes prominent, with about 18 ocelli. Second antennae 

 have the penultimate joint of the peduncle much longer than either of the two 

 preceding joints; rest missing. 



First segment of peraeon, with front angles more rounded than the hinder, a 

 little raised ; the duplicature represented by a long ridge remote from margin ending 

 in a small tooth ; the two following segments each have a short ridge, ending in a 

 tooth ; the sides of the sixth and seventh segments are very much broader than 

 those of the four preceding segments ; in the pleon the third, fourth and fifth segments 

 laterally widen outward. 



The caudal segment is nearly as long as breadth at base, the basal part about 

 one-third of the length, the subquadrate apical part with sides very slightly con- 

 verging to a somewhat arched or obtuse-angled apex, thus supplying a form very 

 unusual in this genus. The segment is not quite flat, but slopes a little from the 

 middle to the sides. 



The uropods with the narrow apical part do not completely fill the space between 

 the terminal and preceding segments. The inner rami reach the apical margin of the 

 caudal segment ; the outer are slightly curved, more than half as long as the peduncle, 

 being attached high up well within its margin, and reaching slightly beyond its 

 apex, though falling considerably short of the inner rami.
