present; cliiu with 2 barbels. Brancbiostegals 6. Soft dorsal and anal 

 long. An imperfectly known genus, evidently allied to Jordania, found 

 in ratber deep water in California, {itapa, near; Icelinus.) 



2208. PARICELINUS HOPLITICUS, Eigenmann & Eigenmaun. 



Head 4 ; depth 6^. D. XII, 19 ; A. 2.3. Body elongate, subcylindrical for- 

 ward, somewhat compressed behind; region between dorsal armature Hat. 

 Snout pointed. Eye large, elevated, 1 in snout, 3i in head. Interorbital 

 region with a deep median groove and 2 shallower grooves, its width less 

 than dio,meter of pupil. Upper jiosterior portion of orbit strongly ser- 

 rate. Posterior margin of preorbital serrate. Suborbital stay with 2 

 strong upward directed spines behind the eye. Top of head depressed, 

 a series of 8 si^ines on either side, tlie posterior 2 removed from the 

 anterior one ; 2 small spines above posterior part of each eye. Mouth 

 large, maxillary reaching to below anterior margin of pupil, 3^ in 

 head. Both jaws with bands of teeth, the outward anterior ones 

 recurved; vomer and palatines with smaller teeth. A barbel on either 

 side of the lower jaw about as long as pupil. Origin of spinous dor- 

 sal above the posterior portion of the opercle, its end above the origin 

 of the anal; caudal broad, rounded; ventrals reaching the second anal 

 ray ; pectoral very broad, reaching the hfth anal ray, A narrow stripe 

 along base of anal naked; jirickles along lateral line enlarged, forming 2 

 series of spinelets along its anterior portion ; 34 pairs of strong recurved 

 spines along the sides of the back. Sides ashy with scattered rusty spots ; 

 a series of conspicuous ijurjjle spots below the lateral line ; lower surface 

 white ; dorsal and caudal marked with rusty bars. Cortez Banks, oil" San 

 Diego, California (Eigenmann); not seen by us. Type, a single well- 

 preserved specimen, 15 mm. long, from the stomach of Scbastodes lens, fioui

705. ALCIDEA, Jordan & Evermann. 



Alcidea, JOBDAN & EvERMANN, uew genus (thoburni). 



Body elongate, with slender and spinous head. Branchiostegal mem- 

 branes broadly united, free from the isthmus. Preopercular spines sim- 

 ple, 3 in number, all directed downward ; a distinct slit behind last gill 

 arch. Teeth in jaws, and on vomer and palatines. A palmate supra- 

 orbital cirrus ; others present on j)reopercl«. Nasal spine strong. Body 

 thickly beset with short, stiff, villiform prickles; a series of plates along 

 each side of base of dorsals, bearing each a strong spine; plates of lateral 

 line spinous. Both dorsals and anal very long ; caudal rounded; pectorals 

 with the lower rays simple, exserted, fn'oduced; ventrals broad, I, 5. 

 Jlcidca differs widely from Icdus in the structure of its ventrals and pec- 

 torals, in the very spinous head, and in the nature of the body covering. 

 It is, however, evidently very close to Parieelinus. If Dr. Eigenmann's
