FEOM THE GULP OF GUINEA. 77 



but was a moderately common sjiecics in some of the tow-nettings in which it occui-red. 

 This species is readily distinguished from either Temora slylifera (Dana) or Temora 

 armata, Claus, by having the last thoracic segment in both sexes rounded at the 

 postero-lateral angles. The first pair of swimming-feet have the inner branches more 

 or less distinctly 2-jointed. The male fifth pair (fig. 1-7) differ somewhat from the same 

 pair of feet in British specimens, but otherwise the ' Buccaneer ' specimens agree with 

 those of the British seas.

Centropucjes brachiatus was observed in 37 tow-nettings, comprising 28 surface and 

 9 under-surface gatherings. The under-surface tow-nettings included two at 3 fathoms, 

 two at 10 fathoms, one at 20 fathoms, two at 25 fathoms, and two at 50 fathoms. 

 14 of the surface and G of the under-surface gatherings were day collections, while 14

 This, thotigh occurring in a considerable number of tow-ncttings, was by no means a 

 common species. The size of the ' Buccaneer ' specimens agreed with those of the 

 'Challenger' collections, viz. 8-lOOths of an inch=about 2 mm. (not 4-4 mm. as stated 

 in the ' Challenger ' Report).
