Malihe vespertilio, CuviEit and Valencienne.s, Hist. Nat. Poiss., xii, 440.— Goode, Bull, vi, U. S. Nat. Mus. 

 (full synonymy). 



A Malthe, with distaiict! between the anterior angles of orbits less than that between 

 the posterior angles; a snhconical process projecting forward from the head, variable in 

 length but longer than in the other species (about one-tenth of total) ; rostral groove longer 

 than broad. Color, graj'ish-biown above, tawny below. 



Radial formula: I). 4; A. 4. 



Specimens were obtained by the Blake at station CLXIX, in 24^ 4G' N. lat.^ 83° 16' W. Ion., 

 at a depth of 36 fathoms, and at station CLXXi. in 24° 43' JST. lat., 83° 25' W. Ion., at a depth 

 of 37 fatlioms. Also, by the Alhatrofis from station 2311, in 32° 55' N. hit., 77=' 54' W. Ion., 

 at a depth of 79 fathoms; from station 2313, in 32° .53' N. lat., 77° 53' W. Ion., at a depth of 99 

 fathoms; from station 2362, in 22° 08' 30" K lat., 86° 51' 15" W. lou., at a depth of 25 fath- 

 oms; from station 2402, in 2So .'56' N. lat., 85° 33' 30" W. Ion., at a depth of 111 fathoms; 

 from station 2404, in 28^ 44' N. lat., 85° 16' W. Ion., at a depth of 60 fathoms; from station 

 2405, in 28° 45' F. lat., 85° 02' W. Ion., at a depth of 30 fathoms; from station 2400, in 28°

HALIEUTv^A, Cuv. and Val. (Figure 403.) 



Balieutwa, CtTVlEit and Valencennes, Hist. Nat. Pois.s. xii, 4.55. — Guntheis, Cat. Fish. Brit. Mus., m, 203. 



Maltheids with subcircular body disk, and slender caudal peduncle, with depressed 

 fi-ontal region and snout rounded and obtuse, and with conspicuous rostral tentacle. Mouth 

 large, palate toothless. Carpus exserted. Gills in 2i pairs. 



This genus was known only from the northwest Pacific, where the Halieutcea stellata, 

 whose dried skin is .so tamiliar in the insect boxes made up for sale to visitors, occurs at 

 considerable depth. In 1889 tlie rnreiitinator obtaineil a new species, pink and crimson iu 

 color, iu the Andaman Sea, in 265 fathoms, which Alcock names Ealieutaia coccinea. (Fig.
