D. 12 (11-14); A. 18 (17-20); P. 13 (11-15); AO 10 (9-11) + 4 (3-5), total 15 (13-16); gill 

 rakers 5 (4-6) + 1 + 10 (9-11), total 16 (15-18); vertebrae 40-41. 



Dorsal origin slightly before midpoint of body and about over a point midway between 

 pelvic and anal origins. One undivided, long, thin supracaudal luminous gland and occasion- 

 ally a very weakly developed, inconspicuous infracaudal gland, in males only. Females bear no 

 caudal luminous glands. 



Size: To about 70 mm. 



Least depth of capture: At surface at night. 



Distribution: Pacific coast of North America from about 50° to 30° N. The seaward range 

 within these latitudes is not well delineated but probably lies within the California Current. 

 Records of occurrences from above 45° N are unreliable unless based on males (see T. taylori).
