1879.] THE COREAN AND JAPANESE SEAS. ■ IQ 



careful manner in which the exact particulars regarding the locality, 

 depth and, in some cases, the temperature of the water have been 

 recorded by Capt. St. John gives additional scientific value to the 

 present collection ; and although it is to be regretted that the labels 

 belonging to a few of the bottles had unfortunately been washed off 

 and lost before the collection was received bv the Trustees, yet Capt 

 St. John assures me that all these specimens were collected in or 

 near the Corean Straits. The only species not obtained in these 

 seas or m the^ Japanese region is the remarkable Crab Gonatonotus 

 pentaffonvso Adams and White, which was dredged in the Javan 

 sen near Biliiton Island, at a depth of 1 2 fathoms 



In the present communication 64 species or well-marked varieties 

 belonging to the Podophthalmia are noticed ; and of these 26 are ap- 

 parently n.w to science, besides which there are several which for 

 different reasons I have refrained from designating by a specific 

 name. The names and the families to which they appertain are 

 given in the systematic list which follows, where also I have noted 

 the localities and the geographical range, when known, 



n a second paper I hope to describe the remainder of the species 

 col ected which beloig chiefly to the orders Amphipoda and Iso- 

 poda and to the Ci.vipedia and Pycnogonida, and are not less in- 

 teresting thnu the Pcaophthalmia.
