ceding. Origin of soft dorsal nearly midway between front rim 'of 

 orbit and base of caudal. Soft anal similar to soft dorsal, but its origin 

 a short distance posterior. Anal spines short, small, second largest, 

 and first inserted about opposite origin of soft dorsal. Short bony keel 

 extending forward to tips of ventrals from origin of spinous anal. 

 Caudal triangular, rather large and lobes pointed. Pectoral long, 

 falcate, and nearly reaching beginning of straight portion of lateral line. 

 Ventral inserted below origin of pectoral and reaching a little over half 

 way to origin of soft anal. Anus midway between bases of ventrals 

 and origin of spinous anal. 



Color when fresh in arrack leaden or grayish-brown above, shot with 

 bluish and purple, and silvery- white extending over lower surface. 

 Basal portions of anterior rays of soft dorsal and anal tinged with pale 

 yellowish. Spinous dorsal and upper portions of soft dorsal dusky. 

 Upper front edge of caudal lobe dusky. Fins otherwise dilute yellow- 

 ish. A small brown opercular spot. Peritoneum pale. Iris pale 

 yellowish. 



Length 11 inches.

Two are young which I wrongly identified as Citula atropos (Schnei- 

 der). The larger of the latter shows: Head 3^; depth lyV; D- VIII-I, 

 21 ; A. II-1, 17; P. ii, 19; V. I, 5; scales 82 in lateral line, and scutes 28; 

 pectoral 1^ in head; ventral 1^; snout 3^, from tip; eye 3^; maxillary 

 2^; interorbital space 3^. Gill-rakers 7 + 16, slender and compressed. 

 Color when fresh in arrack pale leaden or slaty-gray on back and upper 

 surface, lower side and under surface white. Body everywhere more 

 or less silvery, especially below. Side with five broad pale gray 

 vertical bars. Spinous dorsal blackish. Dorsal dusky above, other 

 fins except ventral dilute yellowish. Ventral black, deepest distally 

 and basal portions pale. 



This species, originally from the Red Sea, has not been compared 

 with Sumatran examples. The latter agree with Cuvier's figure,^ 

 except that only the first dorsal ray is elongate and the others are not 

 prolonged into filaments. Caranx cirrhosus Cuvier^' also lacks dorsal 

 and anal filaments and an opercular spot. It is also supposed to be 

 identical. Russell's figure of Tchawil parah^^ is apparently based on
