NEW Sl'KClKS OF I'HILUTIXE laSlIKS. 521 



the orjo-iii of dorsal lo snout and from origin of \eiitvals lo snout is a 

 low even curve. Tlie interorbital spaee is slightl}' and e\enly convex. 

 The snout is lomuled, ils (lei)fh al nosd'il heiiig greater than its width. 

 Prcorbital is ralhei- wide and unsealed, the anterior inaigin net nolelied, 

 its width at angle ol jaw 1.50 in orbit, ils width below middle of eye 

 very little less than its angle. Maxillaiy ending on a line midway 

 between posterior iiosiril and anterior margin oC eve. 'j'lie end of 

 mandible not reaching to orbit. Teeth in a single series in jaws, rather 

 strong, fixed, almost conical, and with a slight cur\e. ■.'() on each side of 

 lower jaw. No teeth on vomer or palatine, dill openings large, ending 

 on a line slightly anterior to orhit. (Jill rakers slender and pointed, the 

 longest about eiiiial to pupil, 14 on lower limb. 



Scales covering entiie body and head except the orbital ring, maxilhuv, 

 and mandibles; the scales are large smooth with their margins finely 

 ctenoid. Fins scaled, except the ventrals ; a high scaly sheath to dorsals 

 and anal. A lai-ge axillary scale at ventrals; scales largest on the median 

 anterior ])art of body ; small scales at base of fins and thorax. Si\- scales 

 between origin of doisal and head and about 13 series on top of head. 

 Two rows of large xales on the preopercle with two or three small scaU's 

 on its lower margin. 



Origin of dorsal fin about the width oi eye posterior to pectoral axil, 

 the first spine being midway between tip of snout and origin of twelfth 

 dorsal spine, the spines giadually increase in length pustcridily, the fiisl 

 spine being l.'M) in eye while the last '2 in head (measured to base of 

 scaly sheath). Soft dorsal rounded, ils longest ray \.2'> in head. The 

 anal is similar in shape to soft doisal, its second spine is ? in head, the 

 longest ray is about equal to longest jay of soft dorsal; origin of secoml 

 anal spine on a line with base of 13th dorsal spine, being midway between 

 end of caudal vertebra and origin of ventrals, the first anal spine is quite 

 a little in advance of the second. (Origin of ventrals midway between 

 first anal spine and tip of snout ; ventrals are slightly filamentous at tip 

 but do not quite reach to anal pore. Pectorals are rounded, the width 

 of their base being ".'..50 in their length. Caudal rounded, scarcely 

 emarginate, the upper lobe the longer, being about equal to length of 

 head. 



Color in life uniform dark brown or blackish. 



Color in alcohol olivaceous black, fins black, operculai- flap black. A 

 black dot at axil of pectorals. No ocelli anywhere. 



Type is No. 4908. A specimen 133 millimeters in length taken by 

 the writer and C. Canonizado at Sitanki Island, Jolo Archipelago, 18 

 July, 1908. 



This species very closely resembles A. inaln^ but is easily distinguished 

 bv the naked orbital rino-
