Parapeneeus barbatus (De Haan sp.). 



De Haau's species is evidently distinct from the affinis to which he 

 referred it, and is apparently closely allied to P. eonstrictus. I have 

 examined specimens from the Bay of Jeddo, Japan, which agree per- 

 fectly with De Haan's figure of P. barbatus and with his description, 

 except that there is no branchiostegial spine, although the margin of 

 the carapax projects forward in a slightly prominent angle beneath the 

 base of the antenna. These specimens resemble P. eonstrictus closely,' 

 and agree with it perfectly in the oral appendages, the number and 

 arrangement of the branchise, epipods, and exopods, and in the ap- 

 pendages of the first pleopods of the male, but differ in having nearly 

 the whole surftice of the carajiax and pleon pubescent. 



Farapenceus anelioralis (Bate sp.) is apparently closely allied to P. 

 eonstrietus, and should undoubtedly be referred here, as should also, ap- 

 parently, P. affinis (M. -Edwards sp.), P. monoce7'os (Fabricius sp.), and 

 P. velutinus (Dana sp.). Several other of the described Pacific Ocean 

 species probably belong to the genus, but it is impossible to determine 

 their afiinities from the published descriptions and figures. 



Parapenaeus Goodei, sp. uov. 



This species resembles P. eonstrictus, and is apparently very closely 

 allied to P. velutinus (Dana sp.), which is described as having the second 

 and third peroeopods subequal and the telson armed with minute spinules, 

 and is figured as having the fourth perseopods fully as long as the fifth ;
