small to count, until just before caudal, where the fin becomes conspicu- 

 ous again, this posterior lobe not so high as the anterior. Anal oppo- 

 site dorsal and similar to it, the first ray close behind vent; caudal free 

 from dorsal and anal, the caudal peduncle truncate at its base. Ventrals 

 of 3 long rays, with a fourth at the inner base of the third; this fourth is 

 probably a rudiment of 2. The ventrals are jugular in position, the rays 

 very long and filamentous, the longest about the body, reaching to the 

 middle of anal fin. Pectorals inserted high, somewhat shorter than head. 

 Vent slightly behind end of anterior \ of total length. Color brown above, 

 sides and below silvery; back and base of anal closely dotted with dusky; 

 dorsal mostly dusky ; caudal pale, dusky at base, with a narrow white 

 cross bar; lower fins pale; the dark marking on front of back assume 

 something of the form of lengthwise streaks. Tropical Pacific ; Bay of 

 Bengal; Philippine Islands; coast of China, etc., east to the coast of 

 Central America, living near the surface in the open sea. Here described 

 from the types of Bregmaceros lathymaster, two specimens, If and 2 inches 

 in length, dredged at Albatross Station 2804, south of Panama, in 47 fath- 

 oms depth. Two others, 4 inches long, found later off the coast of Panama. 

 A recomparison of these latter specimens with Giiuther's * detailed account 

 of B. macclellandii shows no difference whatever, and we regard B. lathy- 

 master as identical with the latter. Giinther counts the scales 64-14; we 

 find 58-14. In our largest specimens the ventrals reach middle of anal. 

 (Named for Dr. John McClelland, of the Bengal Medical Service, who 

 first studied the fishes of the Ganges.)

* The following is Dr. Giinther's account of Bregmaceros macclellandii, taken from speci- 

 mens from the China Sea: 



"B.7; D.I, 16+X+15; A.22+X+20; V.5or6 ; scales 64-14. Occipital ray very slender, 

 longer than head ; dorsal and anal iins depressible in a groove formed by the scales along 

 the bases of these fins; anterior portions of dorsal and anal elevated, connected with the 

 posterior lower portion by a series of very short extremely feeble rays. Vent at end of 

 anterior third of total length. Three outer rays of ventral fins dilated, compressed, sim- 

 ple, much elongate, reaching to or nearly to middle of anal ; the second and third rays 

 sometimes united at base. Silvery, minutely dotted with brown."
