what shorter and marked by a large articulated spine and the finger 

 is much shorter. Probably these males are one instar younger than 

 the adult figured by Chevreux, but the life history should be studied 

 to confirm this. Because an apparent young male has a second 

 gnathopod rather like that of any young Hyale, such as H. media, 

 identification of juvenile males may be impossible. 



Distribution: Seychelles and Chagos Archipelagos; Gilbert Islands; 

 Eniwetok Atoll, Bikini Atoll, Marshall Islands. 



Hyale dentifera Chevreux 



Hyale dentifera Chevreux, 1907, pp. 414-415; 1908, pp. 499-503, figs. 18-20. 



Material: Reish stations E-72 (5), E-73 (2), BE-101 (1). 

 Distribution: Gambler Archipelago; Eniwetok and Bikini Atolls, 

 Marshall Islands. 



Hyale honoluluensis Schellenberg 



Figures 22, 23 



Hyale honoluluensis Schellenberg, 1938a, pp. 69-71, figs. 35b,c. — J. L. Barnard, 

 1955, p. 18. 



Material: Reish stations E-21 (1), E-38 (5), E-50 (4), E-68 (16), 

 E-93 (10), BE-101 (10), E-116 (8), E-118 (9), E-140 (7), E-171 (4). 



Remarks: The spines on the palm of the second gnathopod are 

 much stouter than figured by Schellenberg and the palm of the first 

 gnathopod is defined by a large spine. 



Distribution: Hawaiian Islands; Eniwetok Atoll, Marshall Islands. 



Hyale media (Dana) 



Hyale media (Dana). — Stebbing, 1906, pp. 569-570. — ^Shoemaker, 1935, pp.

Hyale ayeli J. L. Barnard, 1955, pp. 14-15, fig. 7. 



Material: Reish stations E-73 (4),E-77 (4),E-94 (8), BE-101 (22). 



Remarks: Apparentl}^ Hyale ayeli is an excessively setose form of 

 this species. When described, it was compared with figures of H. 

 media published by Stephensen (1949) wherein no setae are present on 

 the hindmargin of article 5 of antenna 2; since then, Rufi'o (1956) has 

 called attention to the resemblance of H. ayeli to a form of H. media 

 figured by him (RufFo, 1950) from Venezuela having a moderate 

 number of posterior setae; Hurley (1957) also shows small posterior 

 bundles of setae. 



The specimens identified herein have vu'tually no setae on the 

 antennal peduncles. Most of the specimens are smaller than 3.8 mm.
