Depth 14 to nearly 21 in total length (19 to 26, according to 

 Weber and Beaufort) ; head 8.1 to nearly 11 in total length and 

 2.75 to 3.86 in trunk; head and trunk together 1.09 to 1.2 in 

 tail, which is from one-half to four-fifths of head longer than 

 head and tnmk together in my specimens; eye small, 10 to 15 in 

 head and 1.6 to 2 in the rounded snout; mouth wide, 2.7 to 3 

 in head, and closing completely; anterior nostrils with a con- 

 spicuous tube, posterior ones with a rim or short tube, according 

 to age ; teeth in jaws in two rows in young specimens, in three 

 rows in older ones, outer row composed of very small, pointed, 

 fixed teeth; inner row or rows of much larger and therefore less 

 numerous, long, depressible canines ; the two outer rows of maxil- 

 lary teeth continued around intermaxillary plate and inclosing 

 two to several larger, depressible canines; vomer with a short 

 row of seven or eight tiny teeth in my specimens ; larger exam- 

 ples have them more numerous and in two rows anteriorly ; both 

 dorsal and anal entirely absent. 



In alcohol a pale yellowish or gray ground color, everywhere 

 reticulated or marbled with more or less anastomosing, dendri- 

 tic, purplish dark markings which are very numerous and 

 coarser dorsally, finer and less numerous below, so that throat 

 and belly are pale. 



I have two small specimens from Sitanki, 153 and 166 milli- 

 meters in length. The smaller one is a female nearly ready to 

 spawn, and her swollen trunk is in very marked contrast to her 

 slender head and tail. This specimen, though very small and ap- 

 parently adult, seems to agree in all essentials with G. marmo- 

 ratus, the head being contained nearly 11 times in total length, 

 and the color being characteristic. A third specimen, locality 

 unknown, 106 millimeters long, agrees with the others except in 

 color; it is blackish brown with numerous darker marblings 

 which are very indistinct on the dark ground color. 



This eel reaches a length of more than two feet (60 centi- 

 meters) and is found throughout the tropical Indian and Pacific 

 Oceans from Zanzibar to the Philippines, Hawaii, Samoa, and 

 the Marquesas.
