Locality. — Puako Bay, Hawaii. 



Dana's specimens were obtained at Hilo, Hawaii, by Dr. C. Pickering. 

 Only one adult specimen was o))tained, but a large numl^er of young- 

 males (tig. 29), which are probably the young of this species, were 

 taken from the following- localities: Between Kauai 

 Island and Modu Maru or Bird Island; north coast 

 of Molokai Island; south coast of Oahu Island. 

 Depth, 6i to 291) fathoms. These young specimens 

 are probably at a stage somewhat later than the 

 young of the tirst and second stages described by 

 Schioedte and Meinert'^' for C. cestrum Linnaeus 

 and ( '. exmiia., because all seyen pairs of legs are 

 present. The pleopods, uropods, and terminal 

 segment are, howeyer, fringed with hairs, and the 

 first and second antennae are yer}- long, the first 

 pair reaching the extremity of the first thoracic 

 segment and composed each of ten joints, the 

 second pair extending to the posterior margin of 

 the third thoracic segment and composed each of 

 sixteen long joints. The eyes are large and post- 

 laterally situated, and the frontal margin of the head is well rounded. 

 The antero-lateral angles of the first thoracic segment are not pro- 

 duced along the sides of the head as in the adult.
