Study of the Marshall Islands material of this genus leads to the 

 conclusion that the specimens listed from there belong to a single 

 species. They vary greatly in color pattern, but intermediates are 

 found that connect C. xenicus, a mature male, with less mature males 

 of D. dorotheae, C. cooki Giinther, and C. cooki as figured by Herre 

 (Field Mus. Nat. Hist. Zool. Ser., vol. 21, pp. 391-2, fig. 35, 1936). 

 These three named forms are believed to represent the same species, 

 Callionymus goramensis Bleeker. In nearly all previous descriptions 

 of this form of callionymid, few comparisons have been made with 

 already described species, mostly because of the confused nature 

 of the literature and the lack of a comprehensive revision. The 

 exact relationship of these four species cannot be determined without 

 large series from Japan, the PhoenLx Islands, Cook Island, and 

 Goram Island. 



However, bringing them together here will at least caU the at- 

 tention of ichthyologists to this group of "species," not previously 

 defined in relation to each other.
