Size: To about 200 mm. 



Least depth of capture: To 155 m at night. 



Distribution: This species is apparently confined to northeastern Pacific Ocean. It is pres- 

 ently known from between about 28° and 40° N and seaward to about 130° W (one specimen 

 known from near 41° N, 146' W). It is mostly confined to the California Current. 



Parvilux boschmai

Fig. 153 — Parvilux boschmai. holotype, 113.0 mm. From Hubbs and Wisner (1964, p. 

 458, fig. 5). 



Description 



D. 16-17; A. 17 (16-18); P. 12 (11-13); AO 6 (5-7M- 7 (6-8), total 13 (12-14); gill rakers (4)5 + 

 1 + (10) 11-12, total 17-18 (one specimen had 4+1 + 10, each side); vertebrae 36-37 (35-38). 



The species Parvilux boschmai was based on the holotype and only known specimen, but 

 12 additional specimens (101-126 mm) were available for the present study. 



PLO, SAO), upper Pol, and Pre touch or are very near lateral line. PO^ high, about on level 

 of pectoral origin and slightly below, rarely on, level of VLO; PO4 usually nearer a vertical 

 from PO.) than from PO.-, but occasionally midway between. VLO midway between, often 

 slightly nearer, lateral line than level of VO, (nearer VOi in one specimen) and usually nearer 

 a vertical from VO, than from VO^. Four VO (holotype has only 3 VO) about equally spaced. 

 SAO series slightly to moderately angulate; SAOj on or a little behind, rarely slightly before, a 

 vertical from VO.-,; SAO- variously somewhat before, on, or behind a vertical from first AOa. 

 First AOa depressed, AOai.o interspace wider than those of remaining AOa. AOp and Pre 

 series usually continuous; Prc^ widely distant from Pre,-}. 



Dn apparently absent; in the original description it was suggested that the Dn, if present, 

 was represented merely by a streak of silvery tissue, but study of the new material shows this 

 streak to be connective tissue. Vn prominent but often well covered with darkly pigmented 

 tissue. 



Perhaps the most significant changes in the original description of P. boschmai are an 

 increase from 3 VO to 4 (although holotype has but 3 equally spaced VO) and reduction in 

 length of supracaudal gland; in holotype this gland was 14.2% of standard length but only 

 8.9% (7.1-11.6%) in the 12 new specimens. 



Certain body proportions are given below, including those for the holotype; the average 

 value is given first, followed by range in parentheses: 



Head length 289 (273-310); head depth 155 (151-169); length of orbit 52 (48-60); length of 

 upper jaw 200 (190-210); prepectoral length 288 (274-304); prepelvic length 401 (388-421 ); 

 preanal length 545 (528-582); predorsal length 440 (414-464); preadipose length 791 (778-811); 

 dorsal origin to pelvic origin 169 (147-176); dorsal origin to anal origin 206 (190-223); length of 



163
