segments are 2/3 the length of the proximal segment. There are also dif- 

 ferences in the structure of antennae II. However, all of them are based 

 on the fact that Stebbing described a young female and Woltereck had a 

 sexually mature or almost mature male. 



Distribution: Found in the southern part of the Pacific Ocean in 

 Humboldt current, near 15° S, 100° W.

2. Genus Paralanceola Barnard, 1930 



Barnard, 1930: 398; Bowman and Bruner, 1973: 22. 



Known from a lone, rather poorly preserved specimen of a sexually 

 immature male, serving as the type specimen for describing the species 

 and separation of the genus. The primary diagnosis is cryptic and the 

 illustration schematic. 



The entire integument, including antennae I, the body of the 

 mandibles, pereopods, and uropods has hexagonal markings. The rostrum 

 is not conspicuous. The eyes are small, consisting of four ocelli with 

 crystalline prisms. 



Antennae I are attached to the anterior part of the head and project 

 forward; the peduncle is two-segmented. Antennae II have a long thin 

 flagellum. Maxillae II have unequal lobes. The maxillipeds have an oval, 

 almost unarmed outer and small, reduced inner lobe. In pereopods I the 

 5th segment is almost not enlarged distally, and the 6th segment is oval. 

 In pereopods III-IV the 4th and 5th segments are oval or distally enlarged. 

 Pereopods V-VII have retractile claws. 



Type species: Paralanceola anomala Barnard, 1930. 



In almost all the characteristic features (including the two-segmented 

 peduncle of antennae I in males), this genus is proximate to the genus 

 Archaeoscina and differs from it primarily in the retractile claws of pere- 

 opods V-VII, bringing it closer to the family Lanceolidae, and the whip- 

 like flagellum of antennae II. However, the retractile claws on the last 

 pair of pereopods are typical not only of the Lanceolidae, but even of 

 the Chuneolidae, Proscinidae, and some Scinidae (genus Ctenoscina). 

 The whiplike flagellum of antennae II is not known for any other hyper- 

 iideans except the Physosomata. Thus the place occupied by Paralance- 

 ola in the system of hyperiideans is fairly indeterminate. Barnard (1930) 

 included it, with some reservations, in the family Lanceolidae. How- 

 ever, a detailed comparison of characters shows that Paralanceola is 

 closest to the Archaeoscina, which permits its inclusion in the family 

 Archaeoscinidae.
