82 BULLETIN OF THE BUREAU OF FISHERIES. 



Skin thick, opaque, a single pore near upper end of gill slit, the lateral line otherwise absent. 



Color in life translucent, thinly flushed with rose-red, the red due in part at least to blood vessels; 

 lips and gill cavity dusky, the marginal half of the dorsal and anal fins posteriorly and the caudal 

 black; the basal parts of dorsal and anal more translucent beneath the black. 



A fine large species, reaching a length of 9 inches. Numerous cot^-pes were taken with the type 

 at station 4797, off Avatcha Bay, Kamchatka; depth 682 fathoms. 



Paraliparis dactylosus Gilbert. 



One specimen 94 mm. long, from station 4781, between Petrel Bank and Agattu Island; depth 

 482 fathoms; the species hitherto known only from the type taken in Monterey Bay. 



Head 21.5 hundredths of length without caudal; depth 17; interocular width 8; depth of head 17; 

 width of head 13; eye 5.2; snout 6; gill opening 5; maxillary 9.5; distance from tip of lower jaw to 

 vent 12; from vent to anal fin 17; upper lobe of pectoral 14; lower lobe of pectoral 15; caudal 8. 



Maxillary reaching vertical from posterior edge of pupil. Gill opening extending down to fourth 

 pectoral ray. Teeth in narrow bands, weakly trilobed. Vent under posterior edge of preopercle. 



Upper edge of pectoral on a level with the lower margin of the orbit; pectoral deeply notched; 

 upper lobe composed of 20 rays and reaching past front of anal fin; lower lobe composed of 6 exserted 

 rays, slightly longer than upper lobe ; the two lobes connected by 7 widely spaced rays. Dorsal and 

 anal connected with the narrow caudal for nearly 0.33 its length. 



In this specimen and in the type of dactylosus the teeth are in moderate bands, the outer teeth 

 smaller, in about 7 or 8 oblique rows in the half of each jaw. Pyloric caeca 18, short, about 0.5 eye. 



In life red, the vertical fins posteriorly black. 



NECTOLIPARIS, new genus (Cyclogasterids;. 



Ventral disk absent. \'ent far forward under the head, in front of pectoral. Pectoral divided. 

 Teeth simple, in narrow bands in each jaw. Pseudobranchiae absent. Branchiostegals 5. Gill opening 

 restricted to a small slit in front of pectoral. A pelagic genus related to Paraliparis but differing from 

 it and the other genera of the family in having 5 branchiostegals and the gill slit restricted to the front 

 of the pectoral . 



Type Necioliparis pelagicus, new species. 



Nectoliparis pelagicus, new species. (Fig. 27.) 



Type 34 mm. long, from station 4785, between Attn and Medni Islands; at an intermediate depth 

 of 300 fathoms. 



Head 25 hundredths of length without caudal; depth 22; eye 7.5; snout 6; pectoral 12; caudal 13; 

 distance from tip of lower jaw to vent 13. Dorsal 53; anal 48; pectoral 19; caudal 6. Fin counts are 

 from cotypes. 



Head moderate; occiput not swollen, snout short, blunt, not overlapping the mouth; jaws equal; 

 maxillary reaching vertical from front of pupil. Nostril single, in a short tube in front of eye. Teeth 

 small, conical, in narrow bands composed of two or three rows of irregularly placed teeth. Opercular 

 flap bound down and hidden beneath the skin; gill opening a small slit in front of the upper 14 pectoral 

 rays. 



Origin of dorsal slightly behind base of pectoral; dorsal and anal joined to caudal for nearly 0.5 

 its length; pectoral divided into 2 wholly distinct lobes, which are not even joined by free membrane; 

 upper lobe reaching nearly to anal fin, composed of 13 or 14 well-developed rays and 2 or 3 rudimentary 

 rays widely spaced but not quite bridging the gap between the two lobes; lower lobe composed of 3 

 or 4 rays, short, variable in length in the cotypes, sometimes as long as the upper lobe. Vent far forward 

 at the throat, well in advance of lo^\■L'r pectoral lobe and immediately behind edge of gill membrane; 

 it is directed forward and concealed beneath a projecting ridge.
