terminal setose spines, and a small spine on tlie exterior margin below the middle of tlie 

 segment ; the 2nd joint has a stout seta on the exterior distal angle. The 5tli pair in the 

 male are somewhat similar to those of Candace pectiuata and Candace pachydactyla; the 

 left foot is 4-jointed, the penultimate bcmg longer than the others, and furnished 

 with a fringe of hairs on the lower exterior margin and a small spine near the interior 

 distal angle; the outer margin of the last joint has a fi'inge of hairs on the upper half and 

 four spines (2 short, 1 long, and 1 intermediate) near the margin of the lower half. 

 There is a small tuft of hairs and a spine on the inner aspect of the same foot ; the right 

 foot termmates in a stout prehensile hand like Candace pect'mata. The posterior thoracic 

 segment has the lateral angles produced into stout prominent spines, which in the male 

 reach to near the end of the first abdominal segment. The abdomen in the male 5-, in 

 the female 3-jointed; the first segment of the female abdomen is about as long as the 

 other two together, stout and rounded, but not produced into angular processes as in 

 Candace pect'mata. It resembles Candace trimcata in this respect, but the middle 

 segment is much shorter than in that species. The abdomen of the female in the 

 ' Buccaneer ' specimens is dark-coloured — almost black, but only the stylets of the 

 male abdomen are dark-coloured. The tail-setse are also dark-coloured and densely 

 plumose. This species is intermediate between Candace pachydactyla and Candace 

 triincata ; its chief distinctive characters seem to be the form of the anterior male 

 antenna and of the male and female fifth feet. 



Hahltat. Lat. 1°55' 5" S., long. 5° 55' 5" E. It was obtained in two tow-nettings from 

 this locality, one from 35 fathoms and one from 460 fathoms. The peculiar arrange- 

 ment of the colour, together with its decided character, make the species, especially 

 the females, quite conspicuous among their confreres.

Candace truncata was a somewhat rare species in the ' Buccaneer ' collection, the 

 tow-nettings described above being the only ones in which it was observed. It never- 

 theless appears to have a wide distribution.
