roof of mouth Ixiliiiul vomer; thvy are direoteil forward, their tip reacliin>r l)a?e of aiitfrinr teetli; 

 ijill-rakers nearly obsolete, 4 or 5 very short movable ones next the angle. 



Porwil (in lieginning on snout imiiieiiiately above anterior nostril; first ray inserted very slitrhtly 

 toward risilit side of ridge; anterior rays joined by membrane at base only, suceeeding rays exserted 

 progressively less; tlie (irst ray is longer than any of those that immediately succeed it, these decreasing 

 rapidly to tifth or sixth ray. then slowly lengthening, the longest rays at lieginning of posterior third 

 of tin; anal tin similar, wilhuut anterior lobe; caudal lanceolate; the anterior two-fifths of base of left 

 ventral lying between interopercles, the liase lying along pre-anal ridge, its posterior membrane very 

 short, attached inunediately behind hist ray, leaving a long free space between ventrals and first anal 

 ray; left pectoral long, about two-thirds length of head; right pectoral shorter than diameter of pupil. 



Scales minute, everywhere cycloid; rays of caudal fin accompanied by series of scales, otlur fins 

 naked; lateral line e(|Ually and similarly developed on both sides, the anterior curve short, rather low, 

 tiat-tiipped, its chord contained (i times in straiglit piirtion of lateral line. 



Color very light brownish olive, everywhere coarsely flecked with light brown; peritoneum blue- 

 black, the color visible through the thin abdominal walls; three irregular dark blotches, with black 

 centers sliading into brown, lie along lateral line, the first small, just behind curve of lateral line, the 

 second and longest in advance of nnddle of straight portion, the third near tail; dorsal and anal 

 finely mottled, with a series of ini'onspicuous large brown spots along basal lialf; caudal membrane 

 blackish; left pectoral dusky. 



The stomach was distende<l with the ])artially digested remains of some lish. Only the type is 

 known. The species differs strikingly from ('. Itigubrls Alcock (Jour. As. Soc. Beng., vol. 63, 1S94, p. 

 129, pi. 6, fig. 4), from the Bay of Bengal. 145 to 250 fathoms, in the shape of anterior curve of 

 lateral line. In C higubris the anterior ])ortion of lateral line is sliarply angulated above base of 

 pectorals, while in C. prorigera there is the flat-topjied curve common among species of Platophrys. 



Pelecanichthys crumenalis (iilbert & Cramer. 



This most peculiar flounder was taken sparingly on sand\- ami muddy bottom at depths of from 

 23S to 344 fathoms. It was found only in the Pailolo Channel and its approaches, and in the southerly 

 continuation of the Kaiwi Channel, where it was originally obtained. Its food con.si.sts of shrim]is and 

 other small Crustacea. The genus is prolialily most closely related to ('li<i!icaii(ij>sefla Alcock. 



Taken at the following stations; Nos. 3839, Pailolo Channel, 259 to 266 fathoms; 3865, Pailolo 

 Channel, 2.56 to 283 fathoms; 3.S66, Pailolo Channel, 283 to 284 fathoms; 3867, Pailolo Channel, 284 to 

 290 fathoms; 3884, Pailolo Channel, 284 to 290 fathoms; 3907, off the south coast of Oahu, 304 to 315 

 fathoms; 3908, off the south coast <:>f Oahu, 304 to 308 fatlioms; 3909, off the south coast of Oahu, 308 

 to 322 fathoms; 3910, off the south coast of Oahu, 311 to 337 fathoms; 3911, off the south coast of 

 Oahu, 337 to 344 fathoms; 3920, off the south <-oast of Oahu, 265 to 280 fathoms; 4U83, off the north 

 coast of Maui, 2.38 to 2.53 fathoms; 4097, Pailolo Channel, 286 fathoms.

Type, 105 mm. long, fi'om station 4114, off tlie nnrthwest ctjast of < lalui, dejith 154 to 195 fathoms; 

 type, No. 51619, U. 8. Nat. Mus. 



Head 4.85 in length to ba.se of caudal; depth 3.28. D. 97; A. s7; V. 4; C. 14; series of scales 

 downw'ard and I)ackward, counted along middle of sides, 113. 



Body of moderate depth, with a narrow truncate caudal base; mouth greatly curved: maxillary 

 reaching vertical from middle of lower eye; eyes very close together, ui>pe'' slightly in advance; pos- 

 terior two-thirds of intemrbital space occupied l)y a rather irregular j)atch of scales which encroach on 

 eyes; lietween anterior iiortions of eyes, the usual broad Hap. beneath which o]iens posterior nostril; 

 anterior nostril in a long tulie immediately aliove upper lip, and slightly nearer lower eye than 

 extremity of snout; on blind side, the anterior nostril t\die is the shorter; jiosterior nostril slit-like, at 

 U]iper end of a vertical fold whicli runs upward from a point in front of angle of mouth.
