lias at the outer ang-le of the basal joint of the first antennae only 

 one denticle instead of the two found in P- sciilptus, the chelipeds 

 also showing- some differences. In Professor Smith's specimen 

 of F- scuiplus the sublateral carina between the cervical groove 

 and hind margin had also 5 small spines on one side and six on 

 the other. The South African specimen has five on ,each side. 

 Smith speaks of the longitudinally-furrowed carina of the sixth 

 pleon segment as " inconspicuous," an epithet inapplicable to it 

 in our specimen. In the fifth pair of legs the finger is notably 

 longer than the thumb, which, though short, is quite distinct- 

 The colouring (in formalin) shows on the carapace three rose- 

 colou'red areas, one central in the front of the cervical groove, 

 and the other two behind it, lateral, of long triangular shape; the 

 ground is a pale dull orange. 



Dimensions: — Carapace in median line, 5625 mm,.; lateral 

 margin, 63-75 "i"''- 'ong; greatest breadth in front of cervical' 

 groove,43-75 mm.; length of pleon, 70 mm.; of second antennae, 

 70 mm. Total extension from apex of second antennae to apex 

 of telson, about 8 inches- Length of first chelipeds, nearly 140 

 mm., reaching, therefore, if fully extended considerably beyond 

 the second antenna, but as preserved they are strongly genicu- 

 late between the third and fourth joints. 



Locality: — Cape Natal N- by E. (approx-) 24 miles. Depth, 

 440 fathoms. Bottom, mud-

Ortmannin iSgj recognizes seven genera, which he arranges 

 in three groups— i Palinurellns, Jams ; 2 Palinunis, P.ilinustus, 

 Linuparus ; 3 Pamdints, Pucrnlus- Of these he says " the first 

 mav be called the more primitive, the second the typical, the 

 third the more advanced group." Of Fadnnstns A. Milne- 

 Edwards, 1880, he remarks that it " comes very near to Palin- 

 urus, and differs only in the weaker ' frontal horns,' which are 

 placed on the outer edge of two very peculiar plates projecting 

 horizontally from the frontal n:\argin and truncajted squarely at 

 the apex." In regard to the fossil species described and figured
