86 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 27 



Harpiniopsis petulans, new species 



(Fig. 39) 

 Diagnosis: Anteroventral corner of head unproduced ; epistome 

 acutely produced anteriorly; article 2 of pereopod 5 broad, produced 

 downward truncately to end of article 4, with 2 small posterior teeth 

 below 4 minute serrations; third pleonal epimeron with a very long 

 posterior tooth curving dorsally ; rami of uropod 2 naked. 



Holotype: AHF No. 60 11, female, 4.5 mm. Unique. 



Type locality: Station 6842, Coronado Canyon, California, 32°- 

 22'-50" N, 117°-22'-12" W, 1265 m, January 31, 1960. 



Relationship: This species differs from Harpiniopsis epistomata J. L. 

 Barnard (1960b) in the immense tooth of the third pleonal epimeron. 

 In that character it closely resembles H. e?neryi J. L. Barnard (1960b) 

 but differs in the acutely produced epistome, the much larger and 

 broader second article of pereopod 5, and the relatively short remainder 

 of the appendage. 



Harpiniopsis profundis J. L. Barnard 

 Harpiniopsis profundis J. L. Barnard 1960b: 330, pi. 66. 



Canyon material: 6844(1), 7049(2). 



Basin material: 2850 ( 1 ) . 



Slope material: 2344 ( ?1 ). 



Harpiniopsis profundis J. L. Barnard var. 



(Fig. 40) 



Diagnosis: Differing from normal adults in (1) the somewhat 

 broader posterior lobe on article 2 of pereopod 5, the more strongly 

 truncated oblique ventral margin bearing shallower teeth; (2) the lack 

 oi spines on the rami of uropod 1. 



Catalogued material: AHF No. 606, male, 4.8 mm. 



Locality: Station 6832, Tanner Canyon, 32°-33'-36"N, 118°-55'- 

 40"W, 1298 m, January 29, 1960. 



Material: Two specimens from the catalogued locality. 



Remarks: Materials under examination from deep waters off Baja 

 California show this juvenile form to be connected to the terminal adult 

 as figured by Barnard (1960b), through enlargement and dispropor- 

 tionment of the teeth of pereopod 5 and the development of spines on 

 the inner ramus of uropod 2.
