 Garman, 1913, p. 14. 



Description. — The readiest field marks for this curious shark are the eel-Uke 

 form of its body and tail, the fish being about fifteen times as long as deep; the fact 

 that there is only one dorsal fin, situated far back over the anal but smaller than the 

 latter; that there are six gill openings on a side instead of five; and that the mouth 

 is more nearly terminal than in most sharks, with the snout hardly projecting 



Fio. 4.— Eel shark iChlamydoaelachtu anguineus). After Qoode and Bean 



beyond it. The pectorals, it may be added, are relatively small; the ventrals are 

 larger and close in front of the anal. 



Size. — The few eel sharks so far recorded have been from 2 to 5 feet long. 



Color. — Uniform brown. 



General range. — Probably cosmopohtan in the deep waters of temperate and 

 tropical oceans. This shark has been taken, on several occasions, in Sagami Ba}', 

 Japan; also off New South Wales, Madeira, and Norway. 



Occurrence in the Gulf of Maine. — A curious eel-like fish found dead in a net 

 near Pemaquid Point, Me., in 1880 " may have been an eel shark, and tliis is its 

 only claim to mention here. It would not be surprising should it stray into our 

 Gulf along the trough of the basin from the open Atlantic, for it is as likely to five 

 off our coast as off any other, so widely separated are the localities of capture, listed 

 above.
