14 Mr. P. W. Bfissett-Smllh on some 



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

 times as long as the body. The arrangement of mouth- 

 organs &c. was not made out, as I did not wish to sacrifice 

 the specimen. 



Length 9 millim. 



Family Chondracauthina. 



Genus Chondeacanthus, La Roche. 

 CTiondr acanthus elongatus, sp. n. (PI. VL figs. 4-6.) 



Several specimens of this species were obtained from the 

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

 and on some of these pigmy males were found attached singly 

 near the genital pore (P]. VL fig. 4). 



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

 dented sides ; median groove dorsally well marked ; it equals 

 one seventh total length. From the front border arise two 

 long, simple, soft antennae, as long as the 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. Thorax giving rise to two 

 pair of slender processes, bifurcating at the ends. Genital 

 segnunt 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 0. alatus, Heller, found 

 by him on a ^^Gadus,^^ which species I have also taken here 

 from gills of Psettodes Erumei. 



3Iale (PI. YI. fig. 6). — Very small, pyriform. Posterior 

 antennw placed at the anterior extremity in the form of short 

 recurved hooks. First maxilliped with thick basal joint and 

 well-marked prehensile simple claws. Second maxilliped 

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

 tinctly segmented ; two narrow, terminal, lanceolate caudal 

 processes. 



Family LernsBopodidae. 



Genus Bkachiella, Cuv. 



Brachiella appendiculosa, sp. n. (PI. VL figs. 1-3.) 



Several specimens of this species were taken from the gills 

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

 nemus tetradactylus. Its characters were well-marked and
