FISHES OF THE rHlLH^'INE ISLANDS AND ADJACENT SEAS 143 



figure differs a little from that published by Hilgendorf in that the 

 second dorsal and anal are shown subequal in size, the pectoral greatly 

 smaller or IIX5 in head so the first dorsal origin would fall about 

 opposite the depressed pectoral tip. Day gives a figure differing 

 from Hilgendorf's in the more advanced first dorsal, the origin of 

 which is shown close behind the narrow pectoral base, the anal length 

 11/2 in that of second dorsal, the small pectoral very slightly longer 

 than that of the head measured to the first gill opening and tlie upper 

 tooth rather broadly triangular and serrated. In his description Day 

 says of the teeth, "none serrated" and that he has obtained specimens 

 up to 1,830 mm. It is quite evident that Garchainas nvunzingeri Koss- 

 mann and Riiuber is intended for the present species, the only dis- 

 tinction seemingly from the very imperfect notice given resting on 

 its larger dorsal fins, the remarks on the dention hardly of any 

 value. 



Garman in describing an example from the Gilbert Islands char- 

 acterizes the labial folds as short, the upper directed outward and 

 a little forward, lower hidden in the angle. He also describes the 

 pectoral width 5f, tlie fin length and the edges of the hindmost fins 

 blackish.

Aprionodon sitankaicnsis Hekre, Fishes Herre Philippine Exped. 1931, p. 11,

Greatest depth equals 11/12 greatest width; head 3%, as measured 

 to fifth gill opening, depressed anteriorly. Snout 2% in head, bluntly 

 rounded; eye 9I/2, small, 21/2 in postocular region measured to first 

 gill opening, and trifle smaller than latter ; mouth arched, nearly long 

 as wide, length Si/o in head, width 3i/io; labial fold in angle of jaws, 

 barely extends upon upper jaw ; teeth 29 above, 31 below, not serrated ; 

 upper teeth nearly erect to somewhat oblique, with broad base having 

 a large denticle on inclined side; lower teeth erect or almost so, with- 

 out serrations or basal denticles; median row of teeth in each jaw 

 small and erect. Last gill opening only % wide as others, and 2 

 posterior gill openings over pectoral base. 



First dorsal little nearer ventral than pectoral, hind edge very con- 

 cave and hind angle produced; second dorsal and anal almost oppo- 

 site, or anal origin very little advanced; hind anal edge much more 

 indented than that of second dorsal; caudal 2I/2 in length; pectoral 

 reaches hind end of first dorsal base, width 1% its length, fin falci- 

 form, with deeply concave hind margin, angles rounded. 



In alcohol blackish slate-blue on upper half, including dorsals, 

 caudal, and upper side of pectorals. Under side whitish. Blackish 

 spot on under side of pectoral tip. Ventrals and anals broadly 

 edged with dusky bluish.
