FEOM THE GULF OF GUINEA. 61 



January 27tli (clay collection). Station 23, surface, 10, 20, 85, and 185 fathoms tow- 

 nettings, February 5th (clay collection). Lat. S" 36' 8" S., long. 12° 57' E., surface, 

 February 9th (clay collection). 



This Ccmdace was obtained from 57 tow-nettings, 24 of which were surface and 33 

 under-surface gatherings ; 37 of the tow-nettings (16 surface and 21 under-surface) were 

 collected during the day, and 20 (8 surface and 12 under-surface) were collected during 

 the night, as shown in the formula : —

The under-surface tow-nettings ranged in depth from 2 to 260 fathoms. Ccmdace 

 pachyclactyla, as noted above, occurred in twice as many day surface as in night surface- 

 gatherings ; its distribution in this respect is thus more or less the reverse of that of most 

 of the species described in this Report.

Habited. Lat. 1° 55' 5" N., long. 5° 55' 5" E., 35 fathoms, January 22nd (day collec- 

 tion). Station 23, surface tow-netting, February 5th (day collection). 

 This Candace was of rare occurrence in the ' Buccaneer ' collections. 



Candace intermedia, n. sp. (PI. IV. figs. 30-37.) 

 ? Candace curta, Dana (1852), Crust. U. S. Espl. Expedition, 



Length, exclusive of tail-seta?, 2'46 mm. In form somewhat like Candace pectinata, 

 Brady, but the posterior margin of the first thoracic segment is produced in the median 

 dorsal line so as to form a distinct hump, which is usually of a chocolate- brown colour, 

 while the surrounding integument is white or nearly so (fig. 56). The last thoracic 

 segment (figs. 62, 63) is furnished on each side with four small hairs, the posterior one 

 being the longest. The 16th, 17th, and 18th joints of the right male antennae are 

 toothed in a manner somewhat similar to that of Candace pectinata, but the teeth on the 

 18th joint (the joint on the distal side of the hinge) do not form a distinct beard-like 

 fringe as in that species. The proportional lengths of the joints, especially of the right 

 male antenna, differ from those of C. pectinata and are very nearly as in the annexed 

 formula : —

The 17th joint in the male is usually dark-coloured. The mouth-organs and swimming- 

 feet, except the fifth pair, resemble those of Candace pectinata. The fifth feet in the 

 female are somewhat like those of Candace pachydactyla, but the terminal spines only
