628 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



along the jaws and extending back to tbe opercle. Scales about as in Maynea, not evident 

 on anterior part of the body in my specimens. Ventrals wanting. No pyloric ca^ca. Intes- 

 tine short. Vent at the end of the first third of length. Dorsal beginning over base of 

 pectoral, continuous with anal, the rays high [Bean). 



This genus is represented by a single species, B. mollis, obtained at Albatross station 

 2860, off Cape St. James, Quecu Charlotte Islands, at a depth of 870 fathoms. 



MAYNEA. 



Two species of this genus were described by Bean from the explorations of the Alba- 

 tross in the Pacilic, as follows: 



M. pusilla, Bean (Proc. U. S. N. M., xiii, 1890, 39), obtained at station 2818, in 110 

 fathoms. 



M. brunnea, Bean (/oc. ci^, 39), obtained at station 2839, off San Clemeute Island, south- 

 ern California, at a depth of 411 fathoms. 



Before Melanostigma insert : 



LYCODAPUS, Gilbert. 



Lycodapus, Gilbekt, I'loc. U. S. N. M., xiii, 1890, 107. 



Body naked. Ventrals wanting. Vertical fins united around the tail. Gill-openings 

 wide, continued forward under the throat; the gill -membranes anteriorly narrowly united, 

 loosely joined to the isthmus by a fold of lax skin. Branchiostegals, six. No pseudo- 

 branchite. Gills, four; a wide slit behind inner arch. Gill-rakers developed. Teeth pres- 

 ent in jaws and on vomer and palatines, none of them enlarged. Vent remote from the 

 throat. 



Eepresented by several specimens from Albatross stations 2980, 3010, and 3072, off the 

 coast of southern California, Washington, and Oregon, 010 to l,OO.j fathoms. 



Page 317: Gramnwnus. Tiie genus appears to have two opercular spines rather than 

 one, the lower being almost rudimentary in 0. ater but more continuous in 0. armatiis. 



Ollgopus ater. See notes by Bellotti on dentition, habits, etc., of Pteridium at rum ( Atti. 

 Soc. Ital. Sci. Nat., April 29, 1888, May 30, 1891. OlUjopHS armatiis [ = rteridium armatiim, 

 Doderlein) is a name based upon a single specimen in the Palermo Museum. The distinc- 

 tive characters proposed by Doderlein for this form are the presence of two distinct opercu- 

 lar spines (the lower one being almost rudimentary in P. at rum) ; the disposition of teeth 

 upon the palatines; the difierent form of the anterior appendix of the swimming badder, 

 and the dark spots on the body, which are more conspicuous than in P. atrum (Doderlein, 

 Descriz. zoolog.-zootom, di una novella specie di pesci dei mari di Siciha. Palermo, ISSG, 

 con fig.). 



Page.318: Saccogastcr maonlatus, Alcock. In addition to the specimens mentioned in 

 the text, an adult male over 3.^ inches long was obtained by the Investigator in the Bay of 

 Bengal, station 120, at a depth of 240 to 270 fathoms. It was upon this specimen that 

 Alcock made the important studies described by him in the "Proceedings of the Zoological 

 Society," April 7, 1891, entitled "On a Viviparous Bathybial Fish from the Bay of Bengal." 

 The species is figured by Alcock (Ann. and Mag. Nat. Hist., July, 1891, PI. vii, fig. 3). 



Cata'tyx riihrirostris, Gilbert (Proc. U, S. N. M., xiii, 1890, 111). Four specimens were 

 obtained from Albatross stations 2909, 2936, and 2925, off the southern coast of California, 

 in 205 to 359 fathoms.

 Sirembo murwnolepis, Vaillant, Exped. .Sci. Trav. et Tul., 273, PI. xxiii, figs. 4, la. Many speciiiieus were 

 obtained off Soudan. 



The name I). Alcockii is proposed for the Andaman form, identified by Alcock with D. 

 brachysoma. 



Page 322: Bassozctus glutinosus. A good figure is given in "Illustrations of the Zoology 

 of H. M. S. Investigator," Part i, PI. i, fig. 3, Calcutta, 1892. An examination of the figure 

 confirms the opinion that this species belongs to the genus Bassozctus, as understood by us.
