posteriorly thau in Syna)iceia. The skin is smooth, and apparently 

 free from dermal flaps and excrescences except at base of dorsal 

 and anal fin. 



Deleastes daector vSeale, new species. 



Depth at origin of dorsal 2.45; head 2.20; eye 8.05 in head, 

 2.20 in interorbital space, 2 in snout; D. xiii, 6; A. iii, 5; inter- 

 orbital space with a deep fossa, also a deep fossa just posterior of 

 each eye. 



Body compressed posteriorly; no scales and apparently no der- 

 mal flaps; head monstrous, without spines; mouth large, opening 

 on the dorsal profile; villiform teeth in both jaws; no teeth on 

 vomer or palatines; the distal width of the maxillary is slightly 

 greater than orbit; dorsal fin continuous, its origin diredtly above 

 the origin of ventrals; the base of the spinous portion of the dorsal 

 is more than four times as long as the base of the soft dorsal; anal 

 short, its base 2.10 in head, the spinous portion covered with fleshy 

 excrescence; the posterior margin of the pectoral is twice the 

 length of the fin, the upper axis of the fin is exadlly over the middle 

 of the posterior margin of the fin and its lower anterior origin is in 

 advance of the origin of ventral, also in front of a line with eye; 

 the posterior margin of the pectoral is slightly greater than length 

 of head; ventrals very short, 2.15 in head; caudal small, rounded, 

 its middle ray equal to length of ventrals; all the fins are fleshy. 



Color in life, mottled everywhere with olive brown or dark 

 green; caudal, pectorals and anal banded with whitish lines. 



In this species the ventrals are smaller, and situated more 

 posteriorly thau in other species of Synanceia, the skin also is much 

 smoother and is apparently free from fleshy excrescences except at 

 base of dorsal and anal. 



One specimen. No. 1360 (Fig. 22) B. M., from Tahiti. Length 

 10.5 in. 



Synanceia verrucosa (Bloch). 



Depth 2.75; head 2.50; eye 9; D. xiii, 6; A. iii, 5; inter- 

 orbital space 4 in head; snout less than width of the interorbital 

 space. 



Body subcylindrical, covered with lichen-like fleshy excres- 

 cences and dermal flaps; head monstrous; interorbital space very 

 concave; a groove on cheeks below the eye and a deep fossa behind 

 each eye; no spines on the head; premaxillary thin, its length 

 2.50 in head; distal width of the maxillary slightly greater than 

 orbit; the anterior extremit}' of the lower jaw is on the dorsal pro- 

 file; villiform teeth in jaws, none on the vomer or palatine; opercles 

 without spines; the dorsal fin is continuous, the spinous portion 

 with much the longest base, the origin of the dorsal is over the
