REVIEW OF THE HAWKFISHES — RANDALL 413 



depth of body about 2.6 in standard length (3% in total length); 

 preopercular margin serrate, rounded, without a concavity. 



Color of body orange-red with 16 to 18 brownish longitudinal 

 streaks, one on each scale row; a U-shaped dark brown mark wider 

 than pupil of eye and edged with orange extending diagonally upward 

 from posterior upper half of eye (after Bleeker). 



Remarks. — Known only from the Sangi Islands, between Celebes 

 and Mindanao. This species has erroneously been placed in the 

 synonymy of arcatus by some authors, probably because of its similar 

 postocular mark. 



Bleeker described a median crest on the head of amblycejjhalus, 

 although there is no evidence of this from his figure. M. Boeseman 

 examined the type (No. 5841), evidently the only known specimen, 

 at the Rijksmuseum van Natum-fijke Historic at Leiden. He reported 

 the specimen, about 78 mm. in standard length, to be in poor condition. 

 The upper part of the head has been skeletonized, and the median 

 crest appears to be only the bony ridge of the supraoccipital exposed 

 by the removal of soft tissue. It was hoped that the position and 

 shape of the postocular mark and the shape of the caudal fin, as 

 described and figured by Bleeker, could be verified; however, the post- 

 orbital part of the head is badly damaged and no color markings are 

 visible. The caudal fin is mutilated.
