1 think that this species can not be Dana's P. velutinus^ as the max- 

 ilhpeds are much shorter and the lateral spines of the telson are very 

 large. Our species, however, coincides with some of the Challenger 

 specimens collected in 8 fathoms in Japanese waters, labeled P. veluti- 

 mis b}' Bate, and presented to the U. S. National Museum. The 

 Japanese form is not that iigured b}^ Bate (pi. xxxiii, fig. 1). His 

 remarks " indicate that he combined a number of species under the name 

 velutimis. 



Kishinouye^ mentions, without description, the occurrence in 

 Japan of some species verj" closely allied to that which he calls 

 Penaeus velutinus; there is one such species (see beloAv) in the Jordan 

 and Snyder collection, and two others in the U. S. National Museum. 

 The four species agree in their pubescence, in the lack of a carina on 

 the carapace behind the gastric spine, and in the long lateral spines of 

 the telson. 



In ParajyenaRus akayehi {— Penaeus velutinus Kishinouye), the ros- 

 trum is horizontal or nearly so, and in adults extends to the end or 

 beyond the end of the second segment of the antennula. Dorsal 

 spines 7 or 8, the posterior spine situated a little in front of the 

 anterior third of the carapace (rostrum excluded). A pair of ventral 

 spines between the bases of the feet of the second pair. The sixth 

 and seventh pleonic segments are elongate; the sixth segment is about 

 three-fourths the length of the carapace. 



Dimensions. — Female, length 87.9 mm., length of carapace and 

 rostrum 31.1 mm., length of carapace 17.5 mm., length of sixth 

 pleonic segment, on median line, 1-1 mm. 



Localities. — Wakanoura, Kii (3 males, 1 female); Onomichi, Bingo 

 (1 female); Kawatana (1 female); Nagasaki, Hizen (•! males, 1 female); 

 Jordan and Snyder, coll. Japan; R. Hitchcock, coll. (1 male, 6 females; 

 types. Cat. No. 26152), Mogi; Dr. F. C. Dale, U. S. N., U. S. S. Palos, 

 collector. 



This species, according to Dr. Kishinouye, is known in Japan as 

 "akayebi." 



PARAPEN.(EUS MOGIENSIS, new species. 



The rostrum is straight, inclined slightly upsvard and does not 

 extend quite to the end of the second antennular segment. Dorsal
