 thousand specimens, and 5596, 20 breeding females and 16 males. 

 Two of these females had an epicarid very closely allied to Dajus 

 siriellae G. O. Sars on the carapace. Gilbert Islands* : H. J. Han- 

 sen (1912) identified specimens from these islands. 



Distribution. — The Philippine and Gilbert Islands. 



Remarks. — Very similar to S. inornata, and like inomata an inshore 

 species, abundant at the surface at night, and a coastal rather than an 

 oceanic form.

Description. — In his Siboga report Hansen (1910, p. 30) divides the 

 species of Siriella into four groups. Using his grouping as a basis, 

 this species belongs to the second group, characterized as follows: 

 End of the telson with three small spines and a single pair of more 

 lateral long spines. Proximal joint of the exopod of the uropods 

 with much more than half of its outer margins furnished with spines, 

 and at least about twice as long as broad. Proximal widened part of 

 the telson with three pairs of marginal spines ; spines along the distal 

 third of the lateral margins of the telson closely set but irregular as 

 to length, as several long spines are found, and between each two of 

 these some, or near the end of the telson only one or two, smaller or 

 small spines are inserted. Both rami of the fourth pair of male 

 pleopods terminating in very modified setae. Pseudobranchial rami 

 of the second to fourth pleopods of the male spirally twisted.
