APPENDIX. 5 1 5 



Bather than assign an Atlantic species to a genus only known from the South Pacific 

 it seems justifiable to provisionally form a new genus for its reception, it being in our judg- 

 ment safer to overestimate diagnostic characters which are supposed to exist rather than 

 to undervalue them and withdraw attention from them by the opposite course. 



We therefore propose for this form the generic name Manducus, characterized as fol 

 lows: Body oblong, compressed, covered with scales except upon the top of the head and 

 upon the ridge of the hack, which is rugosely warted; two rows of spots on each sideof 

 the belly close to the ventral line. Head elongate, conical, much compressed, with thin 

 bones: the cheeks covered with large scales. Opercular hones thin, the mouth anil gill 

 openings very wide Ohderjawfor the most part included, armed with a single row of 

 sharp conical teeth with small ones between them and a double row of eight smaller, but 

 similar ones in front. Upper jaw with a single row of teeth in front similar to those in the 

 lower jaw. followed on either side by a lew very long teeth with others smaller behind. 

 Vomer \\ ith a lew teeth; a row of minute sharp teeth on the palatines, and a row of teeth 

 on the entopterygoids as well as a small similar patch on the upper side of the tongue. Eye 

 moderate. Dorsal in the middle of the back over the space between the ventral and the 

 anal. Pectoral and ventral well developed, the latter narrow and shorter than the pec- 

 toral. Anal lower than dorsal with longer base. Lateral line much as in Oonostoma. 



MANDUCUS MADERENSIS (Johnson). 



Diagnosis: A fish having the body elongate, compressed; its height is included i; 1 , 

 times in its length without the caudal; the length of the head ■"">' times in the same distance. 

 The top of the head is scaleless, armed with two low converging ridges which meet in front 

 of the orbits ("hecks with large scales; profile rather steep and snout short. The eye, 

 which is round, does not reach the profile; its diameter is included about 5 times in the 

 length of the head, its distance from the snout is rather more than its own diameter, and 

 from the jaw rather less. 



The lateral line begins near the edge of the operele, ^ of the height from the outline of 

 the back, and following gently until it reaches the middle of the height under the dorsal, 

 it then runs straight to the base of the caudal. Two rows of photophores, which are silvery 

 or pale steel blue in color, are closely set low down on each side of the belly. The upper 

 row, on which between tilt and 70 spots may be counted, begins at the throat and is con- 

 tinued to the base of the caudal, and the lower row runs along the isthmus between the gill 

 openings and likewise extends to the caudal. » 



Radial formula: I). 11: I'. II); V. 8: A. 33: 0. III + 1D+III. 



Scales undetermined. 



This species is known from a single specimen obtained by Johnson in the market at 

 Puuchal and is now at the British Museum. 



Color blackish, with two rows of silvery or pale blue spots along each side of the belly.

 Lower California. 



Paralepis. In the study of this genus, special attention should be given to the impor- 

 tant paper by Cristotbro Bellotti, entitled '•! Paralepidini del Mediterraneo," in the Atti 

 della Societa Italiana di Sci. Nat., XX, fasc. 1, 1877; and his remarks m the same journal.
