base of first two dorsal spines, downward, behind the eye, over opercle, to its lower margin; a light 
brown transverse band on caudal peduncle. 
The above description is based upon the type, No. 50712, U. S. N. M. (field No. 324), and 8 cotypes, 
all obtained by me at Honolulu. 
178. Teuthis umbra Jenkins, new species. 
Head 3.8 in length; depth 1.7; eye 3.75 in head; snout 1.2; interorbital 2.65; D. ix, 27; A. in, 25. 
Body deeply ovoid, greatest depth at pectoral region; head deep; upper profile nearly straight from 
I tip of snout to interorbital space, then convex to origin of dorsal; jaws low, lower inferior; mouth small; 
interorbital width broad, convex; nostrils small, round, close together, anterior larger, with small, thin, 
fleshy flap; last dorsal spine 1.7 in head, anterior spines graduated to posterior; fifth dorsal ray 1.25; 
third anal spine longest, 2 in head; eighth anal ray 1.5; caudal rather broad, emarginate; pectoral 
broad, a trifle longer than head; ventrals sharply pointed, a trifle less than pectoral, or about equal to 
head; caudal peduncle compressed, 2 in head; caudal spine small, sharp, about 5 in head, depressible 
j in a groove; scales small, finely ctenoid, very small on top of head, breast, and basal portions of ver- 
tical fins; lateral line irregular, arched at first, then sloping down to caudal spine, a good portion. of it 
more or less straight, from below anterior portion of spinous dorsal to below middle of soft dorsal. 
Color in alcohol, more or less uniform dark chocolate brown, outer portions of the fins blackish; 
pectoral pale olivaceous brown; ventrals blackish on outer portion. 
The above description is based upon type, No. 50841, U. S. N. M. (field No. 05363) , 7.5 inches long, 
obtained at Honolulu in 1901 by Jordan & Evermann. Only small specimens were secured by me. 
179. Teuthis dussumieri (Cuvier & Valenciennes). 
Color in life (field No. 140, 6.2 inches long), general color brown with very many narrow longi- 
tudinal wavy lines, olivaceous alternating with light lines; dorsal fin bright; bright light line running 
along its base, below which is a bright golden line; signs of indistinct longitudinal lines parallel with 
body on posterior jiart of fin; anal fin similar to dorsal but darker in color; ventrals dusky, with, 
whitish markings; pectoral olivaceous; caudal dusky with darker spots; a ring of golden around eye. 
Seven examples, 6.2 to 11.75 inches in length, were taken by me; five, 4.5 to 6.7 inches, by the 
Albatross; two, 6 and 6.25 inches, by Jordan & Snyder; and four, 4.43 to 6.86 inches, by Dr. Wood. 
This is a common fish at Honolulu.
