The eye has the effect of hanging on the distally narrowed first 

 segment of the peduncle. In the second antennae the penultimate 

 joint of the peduncle is about five times as long as the ultimate as 

 compared with about three times in the type-species. The fiagella 

 were imperfect. 



The epistome is divided transversely by a curved ridge which 

 bounds a cavity expressly excavated, it would seem, to receive the 

 extension of the third maxillipeds, since all the other mouth-organs 

 were confined within the buccal frame. This narrows slightly to the 

 rear. The mouth-organs agree very nearly with those figured by 

 de Haan for the genus Homola, except that he does not show the 

 curious triangular expansion of the exopod exhibited by this species in 

 the first maxilliped. The mandibular palp is three-jointed. The 

 palp of the first maxilla also appeared to be three- jointed, with the 

 third joint wider than the second, but it is rather difficult to make 

 sure of the true articulation in this membraneous appendage. In the 

 second maxilliped the sixth joint is larger than the fifth or the seventh. 

 In the third maxilliped the seventh joint is longer than the sixth, 

 which in turn is longer than the fifth ; the third and fourth joints are 

 subequal in length and breadth, both strongly setose on the inner 

 margin and denticulate on both margins ; the long joint of the exopod 

 does not nearly reach the produced inner angle of the fourth joint of 

 the endopod. 



The rather slender chelipeds have the fingers fitting closely 

 together, two-thirds the length of the palm, equal to the fifth joint, 

 the whole hand rather longer than the fourth joint, Avhich is not very 

 strongly spinose. The second and third peraeopods are much longer 

 and stronger, with prominent spines on the fourth joint, the finger as 

 long as the fifth joint, about half as long as the sixth, its inner 

 margin furnished with about a dozen graduated spines, increasing 

 in length towards the horny nail ; the fourth pair are similar 

 in pattern but rather longer and stronger. In the type-species the 

 sixth joint of these limbs is said to be three times instead of twice the 

 length of the fifth. 



The fifth peraeopods are much slighter than the three preceding 

 pairs, but somewhat longer than the chelipeds, this superiority 

 depending on the considerably greater length of the fourth and fifth 

 joints, the latter two-thirds as long as the former and rather more 

 than twice the length of the curved subchelate hand. The base of the 

 hand is widened and furnished with strong spines, among which the 

 curved spinulose finger can impinge its apex. It is rather interesting 

 to note that this apparatus, prevalent in the Hoinolidae, together
