Description 



D. 11-12; A. 20-21; AO 13-14 (rarely 15); gill rakers 3-4 + 1 + 13-14, total 17-19; vertebrae 

 36-37. 



PrCi.2 interspace notably less than that of last AO-Prci; usually 3 AO behind end of anal 

 base. Body depth greater than 25*^ of SL. PVO2, VLO, SAOi.^ usually in a straight, nearly 

 horizontal line, SAOn only slightly above this line. SAO, nearer VO:) than to VOj. SAO, -2 

 interspace only slightly greater than that of SAO^.:!. 



Supracaudal glands of males single, prominent, heavily bordered with dark pigment (Fig. 

 3); infracaudal glands of females elongate, oval, lightly outlined in black. 



Size: To about 40 mm. 



Least depth of capture: To 100 m at night. 



Distribution: Apparently circumglobal between about 45° and 50° S. In the eastern Pacific 

 the species occurs off Chile, where it maybe abundant. Craddock and Mead (1970) reported the 

 capture of 376 specimens at 37 stations between about 30° and 35° S, 72° and 92° W.

Description 



D. 1 1-12; A. 24-25; P. 14-15; AO 17-19; gill rakers 3-4 + 1 + 12-13, total 16-18; vertebrae 

 40-41. 



Pre,.; interspace about equal to that between last AO and Pre,; usually 6 AO behind end of 

 anal base. Body depth slightly less than 25% of SL. PVO,, VLO, SAO,., in a usually straight, 

 nearly horizontal line, SAO,, slightly above that line. SAO, usually nearer VO2 than to VO3. 

 SAO 1.2 interspace much greater than that of SA02-,i. 



Supracaudal glands of males single, small, heavily bordered with black (Fig. 3); in- 

 fracaudal glands of females small, consisting of 2 or 3 rounded spots, lightly bordered with 

 black. 



Size: To about 35 mm. 



Least depth of capture: At surface at night (Andriashev, 1962); the specimen off Chile was 

 taken in a nighttime haul to 1,000 m. 



Distribution: Poorly understood, but probably circumglobal between about 50° and 55° S. 

 Like P. (H.I subparallelum, it occurs off Chile but possibly in smaller numbers; Craddock and 

 Mead (1970) reported the capture of one specimen at 33° 31' S, 77° 29' W.
