FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 71 



Depth 5% to siibcaudal origin ; head 4%, width little over half its 

 length. Snout 2 in head; eye 12, 5 in snout; preoral length 4i/2 in 

 head, little over half mouth width; labial folds well developed, 

 widely separated across symphyseal space; teeth multicuspid, cusps 

 subequal or graduated to strongest, which not median one ; nasal cir- 

 rus extends to oral edge of nasal valve; interorbital moderately ele- 

 vated. Last 2 gill openings closer, above pectoral, others equidistant. 

 Spiracle minute, close behind eye. 



Fins pointed ; first dorsal origin opposite ventral origin, fin length 

 1% in head, base length greater than interdorsal space; second dor- 

 sal length 1% in head; anal length 1%, origin opposite middle of 

 second dorsal base ; pectoral 1%, width 1% its length which half way 

 to ventral; ventral length 1% in head; caudal 1% in rest of body, 

 front edge of subcaudal 1% in head, notch beyond last eighth its 

 length. 



Brownish. Length, 700 mm. (Regan; Rlippell.) 



Red Sea, Madagascar, India, Ceylon, Pinang, Singapore, East 

 Indies, Queensland, Melanesia. I am uncertain of Garman's Nebro- 

 des macrurus as a distinct species. The main distinction he gives is 

 its greater interdorsal space. Truly, in Riippell's original figure of 

 Nehrius concolor this is shown as not equal to the base length of the 

 first dorsal, but then I can not help but suspect this may be an error 

 of the artist. This is surely likely if we consider the comparative 

 crudeness of Riippell's figures. In 1888 Day gives a figure, though 

 crude in many ways, that is still closer to Garman's and is especially 

 in agreement with its greater extent of the interdorsal space. Regan 

 in 1908 in listing an example of 660 mm. from Java and one 700 mm. 

 stuffed, from Pinang, gives a description in which he states the base 

 length of the first dorsal is greater than the distance from the sec- 

 ond. Though Day says the "caudal fin one-third of the total 

 length," he shows it in his figure as 3%- Garman's reference to 

 "Riippell, 1837, Beschr. Chondropt., p. 2, pi. 17, fig. 2" I have not 

 seen. Though he gives 1838 for the "Fische des rothen Meeres," my 

 copy is dated 1835. 



NEBRIUS MACRURUS (Garman) 



Nebrodes macrurus Garman, Mem. Mus. Comp. Zoo!., vol. 36, p. 58, pi. 8, figs. 

 7-10, 1913 (type locality; Port Louis Harbor, Mauritius). 



Depth 6 to subcaudal origin; head 5%. Snout 2 in head, short, 

 blunt; eye III/2, 5% in snout; 5 in mouth width; mouth moderate, 

 nearly transverse, nearer snout end than eye; labial folds strongly 

 developed, widely separated across symphyseal space; teeth in 30 

 rows above, 28 below, one transverse series functional, much com- 

 pressed, each with low median cusp at each end of which 4 or more 

 smaller ones gradually decreasing in size toward outer; nostrils near
