FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 77 



gill slit 21/^ in last, which IV3 in snout, fourth and fifth closest and 

 over pectoral base. Spiracle minute, below and behind eye. 



First dorsal slightly postmedian, front fin edge li^ in head; 

 second dorsal begins close behind anal base, front fin edge 11/5 in 

 head ; caudal length 414 in^ rest of fish, and subterminal notch below 

 about last fifth; anal length I14 in head; pectoral 1% ; ventral ll^. 



Pale gray tinged with brown, almost white below, especially before 

 ventrals. Ten rather indeterminate rusty brown bars on sides, mostly 

 subtriangular, with apices not or occasionally reaching belly pro- 

 file and their broad bases confluent on back. One bar shade darker 

 forms ill-defined nuchal collar, tapering on sides and ceasing at 

 horizontal level of pectoral origin, embracing posterior 3 gill slits. 

 Sides and back with very numerous scattered small dark brown 

 spots, somewhat darker on body bars ; about 50 on either side between 

 verticals from dorsal origins. Dorsal and lateral surfaces of head 

 in advance of spiracle uniform dark brown. Wliole ventral surface 

 of head whitish, except light slate-gray preoral region. Dorsals 

 largely concolorous with body bars, lighter on hind border, each fin 

 with 10 or 12 dark spots. Anal like ventral surface of body, with 

 one large elongated and 3 or 4 small rounded dark spots. Upper 

 half of caudal like body bars, with dark markings like several small 

 longitudinal stripes along upper border, lower half paler, with a 

 number of subcircular dark spots. 



Length, 710 mm. (Scott.) 



Tasmania. Distinguished from other species by the slightly post- 

 median insertion of the first dorsal. From P. variolatimi and P. fer- 

 Tugmeinn it is distinguished by having the anal inserted wholly 

 before the second dorsal. It differs from P. coUare in having the 

 nasal cirrus reaching the lip, first gill opening nearer spiracle than 

 pectoral and in the concave hind dorsal edges. 



Genus BRACHAELURUS Ogilby 



Brachaelurus Ogilby, Proc. Roy. Soc. Queensland, vol. 20, p. 27, 1907; vol. 21, 

 p. 2, 1908. (Type, Brachaelurus colcloughi Ogilby, orthotypic. ) 



Cirriscyllium Ogilby, Proc. Roy. Soc. Queensland, vol. 21, pp. 2, 4, 1908. (Type, 

 Chiloscyllium modestum Giinther, orthotypie.) 



Heteroscylliiim Regan, Ann. Mag. Nat. Hist., ser. 8, vol. 2, p. 455, 1908. (Type, 

 Brachaelurus colcloughi Ogilby, virtually. Heteroscyllium Regan proposed 

 to replace Bracfiaelurus Ogilby, 1908, considered generically distinct from 

 same name of 1906.) 



Body elongate, depressed anteriorly, partly cylindrical posteriorly. 

 Head broad. Snout short, blunt, wide. Eyes small. Mouth mod- 

 erate, transverse, with labial folds on both jaws, around angles and 

 with symphyseal fold but no fold across chin. Teeth small, tricuspid. 

 Nostrils near snout end, with nasoral grooves and long, slender cirri.
