aloiis' the jiiws and extemling back to the opercle, Scales about as in Maynea, not evident 

 ou anterior part of the body in my specimens. Ventrals wanting. No pyloric cieca. Intes- 

 tine short. Vent at the end of tlie 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. molli.'i, obtained at Albatross station 

 2860, off Cape St. James, Queen Charlotte Islands, at a depth of 87G fathoms. 



MAYNEA. 



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

 tross in the Pacific, as follows: 



M. pusilla, Bean (Proc. TJ. S. N. M., xiii, 1890, 39), obtained at station 2848, in 110 

 fathoms. 



71/. brunnea, Bean [loc. c(7., 39), obtained at station 2839, off Sau Clemente Island, south- 

 ern California, at a depth of 414 fathoms.

LYCODAPUS, Gilbert. 



Lij(0(1aptis, Gilbert, Proc. 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- 

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

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

 throat. 



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

 coast of southern California, Washington, and Oregon, 610 to 1,005 fathoms. 



Page 317: Grammnnus. The genus appears to have two opercular spines rather than 

 one, the lower being almost rudimentary in 0. (iter but more continuous in 0. ar)iiatiis. 



Oligopus ater. See notes by Bellotti ou dentition, habits, etc., of Pteridium atruni ( Atti. 

 Soc. Ital. Sci. Nat., April 29, 1888, May 30, 1891. OUf/opiis armatm { — Pteridium armatum, 

 DiJderlein) 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. atrum); the disposition of teeth 

 upon the palatines; the different 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 Sicilia. Palermo, ISSG, 

 con fig.). 



Page.318: Saccogaster maculatus, Alcock. In addition to the specimens mentioned in 

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

 Bengal, station 120, at a depth of 240 to 276 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 ot Bengal." 

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



Cafa'ti/.r rubrirostris, 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 muramolepis, Vaillant, Expo<l. JSci. Trav. et Tal., 273, PI. x.viii, figs. 4, 4;i. Many specimeus were 

 obtained off Soudan. 



The name D. Alcoclii is proposed for the Andaman form, identified by Alcock with i>. 

 brachysoma. 



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

 of U. 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.
