Order JUGULARES 

 Family TRICHONOTIDAE 



The reference of genera to this family or relationship by various 

 authors from time to time has frequently been the result of inadequate 

 material for comparison of anatomical characters. The genera cen- 

 tering around Kraemeria have features that resemble the trichonotids 

 more than the gobiids, and this has influenced me to place ihem in a 

 subfamily. However, Paragobwides Kendall and Goldsborough has 

 been referred to this group by Fowler, but it certainly does not re- 

 semble any of the trichonotids except by its elongated body and 

 numerous fin rays. A series of pores over the eye, no lateral line, and 

 the restricted gill opening cause me to conclude that Paragohioides 

 is nearer the Gobiidae than the Trichonotidae. Its true relationship 

 will be determined no doubt from a study of its skeleton, and until 

 that is done I propose to consider it tentatively as a distinct sub- 

 family. I am inclined to believe that Hora,'' in referring Para- 

 gohioides to the subfamily Taenioidinae under the Gobiidae, is 

 close to the true relationship. 



In order to separate the various genera referred to the family at 

 various times (from a practical viewpoint) and to indicate some of 

 the relationships with my Samoan and Phoenix Island material, I 

 have prepared a key and incorporated the various genera as noticed 

 by me in the literature.
