shaped hairs ; the others, which occupy the rest of the surface, are long and slender. 

 The endopod rises straight upwards from its articulation and having reached the 

 upper level of the telson bends abruptly backwards in a right angle. It is a solid 

 structure and is beset with setae like the last segment of the exopod. The setae on 

 its upper surface form a dense brush. 



Miers states that his largest specimen was about 29^ mm. in length. 



The only example in the collection is aco-type presented by the British Museum : — 

 7 |p (Locality ?) British Museum (H.M.S. ' Herald'). 1 <S , 24 mm. 



The locality at which the type specimens were obtained is unfortunately unknown, 

 and since the species was originally described it has only once been found : Nobili 

 (1907) records a single small example from Matakea in Polynesia, N.E. of Tahiti.

The carapace is a little longer than broad and its posterior margin is concave. 

 The anterior margins on either side of the rostrum are also concave and do not protrude 

 forwards ; the subacute anterolateral angles are consequently not in advance of the 

 rostral base. The rostrum is trispinous and the sharp lateral spines are only a trifle 

 stouter and shorter than the slender median one. The undivided basal part of the 

 rostrum is short and wide, its length being much less than that of the median spine. 



The dorsal processes of the ophthalmic somite can be clearly seen between the rostral 

 spines. They consist of a plate, straight in front except for a narrow median incision, 

 with sharp anterolateral angles that project transversely outwards almost as far as the 

 external edge of the basal part of the eyestalk. The eyes themselves are cylindrical 

 and in length about one-third the median length of the carapace (a trifle longer in small 

 specimens) ; the cornea is scarcely wider than the stalk and is set very obliquely on it. 

 The eyestalks extend to a little beyond the second segment of the antennular peduncle. 



The mandibular palp is composed of only two segments. 



The basal part of the dactylus of the raptorial claw is strongly swollen, the distal 

 portion is slender and slightly curved. 



The lateral margins of the sixth thoracic somite are broadly rounded, those of the 

 seventh truncate with rounded angles, those of the eighth subacute. 



The median portions of the first five abdominal somites are entirely smooth except 

 that each bears four minute and very obscure pits in a transverse line near the anterior 

 margin, while three others, a central and a pair of lateral, may be found in the middle 

 of each somite except the first. In all these five somites there is a well-defined ridge
