Radiographs of the specimens available to me in this relationship 

 have revealed that in those species now referable to Chorististium, 

 all have VI-I-I dorsal spines, the seventh being embedded. Also, the 

 vertebrae for each specimen numbers 10 + 14=24. As a result of my 

 study of additional material now available to me, I present a new 

 analysis of genera and species in the following key. 



KEY TO GENERA AND SPECIES RELATED TO CHORISTISTmM 



la. Spiny dorsal fin continuous with soft dorsal by a ridge of scales along 

 sides of connecting dorsal spines; no scaled area separating spiny 

 and soft dorsal rays; 8)2 to 5J'2; scales in a row from lateral line to 

 base of last dorsal spine; 16 to 21 predorsal scales to occiput. 

 2a. Dorsal spines VIII (genus Pikea) 3' 



3a. Anal rays 111,10; dorsal rays VIII,14; pectoral ii,14; pores in lateral 

 line 47; zigzag scales around caudal peduncle about 40 to 42; 

 outer edge, distaUy, of each caudal lobe white. (Japan.)
