Figoee 66. — Stomioides nicholsi, Browns Bank. Drawing by Myvanwy M. Dick. 



Stomias. Stomioides resembles Stomias in all other 

 respects so closely that should a specimen of either 

 be taken, that is not easily identified, we suggest 

 forwarding it to the U. S. Fish and Wildlife Service 

 for naming. 



Color. — Black below as well as above, the 

 luminescent organs showing as whitish dots. 



Size. — The only specimen yet seen is about 10% 

 inches long, from tip of snout to base of tail fin. 



Range and occurrence in the Gulf of Maine. — The 

 only known specimen of this species was taken 

 from the stomach of a swordfish harpooned from 

 the schooner Barbara, Capt. C. A. Turner, on the 

 southeastern edge of Browns Bank," over the 

 250 fathom line, August 3, 1932. Presumably it 

 had strayed from the mid-depths offshore. 



Trigonolampa miriceps Regan and Trewavas 1930

 No. 6, 1930, p. 55, pi. 1, fig. 1. 



Trigonolampa resembles Stomias in general 

 appearance, in the relative sizes and locations of 

 the fins, and in having a long fleshy barbel on its 

 chin. But it not only has a small light organ below 

 the eye (as in Stomias), but also has a small 

 luminescent patch close behind it, and likewise a 

 larger triangular patch extending from close behind 

 the eye back across the top of the cheek; these are

its most distinctive characters. The one species of 

 the genus yet known differs further both from 

 Stomias (p. 147) and from Stomioides (p. 147) in a 

 considerably deeper body (cf. fig. 67 with figs. 65, 

 66) ; also in that the tip of its lower jaw does not 

 enclose the tip of its upper jaw when the mouth is 

 closed; that the point of origin of its dorsal fin is in 

 advance of its anal fin by a distance about as great 

 as the diameter of the eye; and that it has only 

 about 68 light organs in each of its ventral rows, as 

 against 85 or 86 in Stomias (p. 147). 



Color. — Not known, but probably black or very 

 dark brown. 47 



Size.- — The largest specimen yet seen (in the 

 Museum of Comparative Zoology) is about 9 

 inches (230 mm.) long to the base of the caudal 

 fin. 



Range and occurrence in the Gulf of Maine. — 

 Only three specimens have been seen yet. The 

 first was taken in the eastern Atlantic by the 

 Danish research vessel Thor in 1906 at a depth of 

 about 600 fathoms; a second was found by Capt. 

 John Toothaker in the stomach of a swordfish 

 harpooned on the southern edge of Georges Bank 

 in the summer of 1922, 48 and a third, now in the 

 Museum of Comparative Zoology, was recorded 

 simply as taken on Georges Bank about 1913. It 

 reaches the slope of our outer Banks only as a 

 stray from the mid-depths offshore. 



" One that we have seen Is brown below as well as above wherever the skin 

 Is intact, with the light organs showing as darker dots. 



" Parr (Copela, 1933, No. 4, p. 178) has given a detailed description of this 

 specimen, which is new in the Museum of Comparative Zoology.
