with M. ivoora, Bleek. The fact that Cuvicr ascribes three pyloric 

 appendages to one species, and five to the other, deserves particular 

 attention. M. adamsii, Richardson, does not differ from M. mono- 

 dactyhis.

The interocular space is two-thirds the width of the orbit ; the 

 posterior prasorbital spine is feeble, and directed downwards. Dorsal 

 spines exceedingly feeble, and produced into filaments. (Schleg.)

Although ignorant of the structure of the gills, I would refer the 

 following species, for the present, to this genus, from which, however, 

 it appears to differ generically in having a distinct anterior dinsion 

 of the spinous dorsal. 



3. Minous trachycephalus. 

 Aploactis trachycephalus, Bleeker, Celebes, vi. p. 451.

The interocular space concave, one-half the diameter of the eye ; 

 head with numerous conical tubercles ; the pra;or])ital with a single 

 short spine ; the length of the pectoral fins is 3|^ in the total. {Bl.)

 Pelor, Cuv. 8f Val. iv. p. 427. 



Head irregularly formed ; scales none ; body, head, and fins with 

 skinny flaps. The three anterior dorsal spines joined by a membrane, 

 ■ and rather remote from the others, which, twelve or fourteen in 

 number, are isolated from one another. Two pectoral appendages, 

 joined at the base by a membrane ; ventrals thoracic. Villiform 

 teeth in the jaws, on the vomer and the palatine bones. Branchio- 

 stegals seven ; air-bladder present, small ; pyloric appendages in 

 small number.
