BRACHIELLA APPENDICULOSA (Kr)<yer). 

 Anchorelln appendiculosa Kr0yek, 1863, p. 306, pi. 16, fig. 6, a to c. 



Host and record of sj^ecimens. — Kr0yer took a single specimen of this 

 species in April, 1853, at New Orleans, Louisiana, from the gills of a 

 fish, "a Corvina or possibly a PageUus, because I have no certain 

 recollection of it and made no written notes." 



Specific characters of female. — Cephalothorax longer than the trunk 

 and made up of two parts, an elongated head covered with a brown 

 carapace, and a thick, wrinkled neck; trunk thick and broad, obcor- 

 date in outline; four cylindrical posterior processes, the dorsal pair 

 somewhat smaller than the ventral and farther apart, the ventral pair 

 nearer together and longer than the trunk; genital process short and 

 nearer the dorsal surface; egg strings large and a little longer than the 

 processes. 



Second antennae biramose, turned down across the frontal margin, 

 the posterior or ventral ramus a little smaller and apparantly three- 

 jointed. First antennae close to the mouth-tube near its base, two- 

 jointed, the joints standing almost at a right angle to each other. 

 Second maxillae three-fifths as long as the cephalothorax, situated at 

 the posterior end of the neck, close to the trunk. Each maxilla is 

 broad at the base and pointed toward the tip, where it is attached to a 

 small, spherical bulla. 



Maxillipeds large and prominent, the basal joint armed on the inner 

 margin with roughened knobs and spines, the terminal claw with an 

 accessory spine on the inner margin near the base. 



Color, milk-white. 



Total length, 8.75 mm. Cephalothorax, 4.85 mm. long. Trunk, 

 3.90 mm. long. Posterior processes, 4.25 mm. long. 



(appendiculosa, with many small appendages). 



RemarTcs. — This species has never been seen by any investigator 

 other than Kr^j^-er, but his description and figures are sufficient to 

 establish the validity of the species, and since it was obtained at New 

 Orleans it must be included in our North American forms. 



There is good hope that it may be rediscovered when the fish of that 

 localit}^ are more carefully examined. 



BRACHIELLA GRACILIS Wilson. 

 Brachiella gracilis Wilson, 1908, p. 464, pi. 77. 



Host and record of specimens. — Both sexes and several develop- 

 mental stages were taken by Dr. J. F. McClendon from the mouth of 

 the white sea bass, Cynoscion nohilis, at La JoUa, California. 



These were made the types of the species and were given Cat. No. 

 38577, U.S.N.M. 



RemarTcs. — This species was fully described and figured in the refer- 

 ence given above. It may be recognized by the length and slender-
