end with a third longer side branch. Egg-sacs three or more 

 times as long as tlie body. The arrangement of moutli-

Family Chondracanthina. 



Genus Chondracanthus, La Roche. 

 Chondracanthus elongatus, sp. n. (PI. Yl. figs. 4-6.) 



Several specimens of this species were obtained from the 

 gills of a sole (sp. ?) at Bom.bay. Most were mature females, 

 and on some of these pigmy males were found attached singly 

 near the genital pore (PI. VL fig. 4). 



Female. — Length 6 millim. Head oblong, with greatly in- 

 dented sides ; median gioove dorsally well marked ; it equals 

 one seventh total length. From the tront border arise two 

 long, simple, soft antenna3, as long as tlie head. Posterior 

 antennce placed immediately behind them in the form of two 

 long slender hooks. Mouth-organs, as in others of this 

 genus, placed near the neck. Tliorax giving rise to two 

 pair of slender ])rocesses, bifurcating at the ends. Genitjl 

 segment elongated, cylindrical, with posteriorly two simple 

 elongate processes, rather more than one third length of that 

 segment. Abdomen short, rounded. Caudal plates simple, 

 one third length of posterior appendages. 



This species resembles somewhat C alatus, lleller, found 

 by him on a ^^GaduSj'' which species I have also taken here 

 from gills of Pseitodes Erumei. 



Male (PI. VI. fig. 6). — Very small, pyriform. Posterior 

 antenncB placed at the anterior extremity in the form of short 

 recurved hooks. First maxiUiped with thick basal joint and 

 well-marked prehensile simple claws. Second maxiUiped 

 more attenuated, with a simple straight spine. Body indis- 

 tinctly segmented ; two narrow, terminal, lanceolate caudal 

 processes. 



Family LernaEopodidae. 



Genus Brachiella, Cuv. 



Brackiella appe?idiculosa, sp. n. (PI. VL figs. 1-3.) 



Several specimens of this species were taken from the gills 

 of fish in Bombay llarbour, viz. Stromateus niger and Poly- 

 nevius tetrudactyhis. Its characters were well-maiked and
