 longer than 5th but shorter than 6th, hind margin strongly spinose, 

 finger as long as 6th (5th-7th joints in 3rd peraeopod lost.) 



Fifth peraeopod, 2nd joint 2 times as wide proximally as distally, 

 hind margin nearly straight, very faintly serrulate, 3rd-7th joints 

 lost. 



First and second uropods, rami narrow, finely pointed, outer a little- 

 longer than inner, feebly spinose. 



Third uropod lost. 



Length : 9 mm. 



Colour: In spirit, whitish. 



Locality: Cape Point N.E. by E., distant 36 miles. 650 fathoms. 

 3 mutilated specimens (one of them a $ , other two uncertain), s.s. 

 " Pieter Faure." 15/7/03. (S.A.M. No. A2794.) 



Specific name referring to the mandibular palp, which forms one of 

 the distinguishing features of the species. The other features are : 

 the absence of eyes, the shape and size of the 5th and 6th joints of 

 the 1st and 2nd gnathopods, the 2nd joint of the 3rd and 4th 

 peraeopods, and the telson.

Since in the single specimen the 3rd uropods have been broken off, 

 it remains uncertain whether the species is rightly assigned to this 

 genus. The pi-ocess of the 5th joint of the 2nd gnathopodis certainly 

 like that of H. aequicornis as figured by Sars, but the telson is 

 reminiscent more of Westwoodilla.
