Remarks. — The occurrence of both Kraemeria samoensis and K. hryani 

 in the northern Marshall Islands is the first time both species have been 

 reported in the same general locality. This indicates that K. hryani 

 may have a wide range in the tropical Pacific. 



KRAEMERICUS, new genus 



Type species. — Kraemericus chapmani, new species. 



This new genus is characterized by its two dorsal fins; dorsal and 

 anal fins free from caudal fin; gill openings extend far forward along 

 isthmus, with gill membranes free from isthmus; body scaled; no lateral 

 line; tongue bilobed at tip; lower jaw longest swollen at tip, entering 

 dorsal profile; eyes lateral in position; inner pelvic ray longest; gill 

 rakers obsolete. 



This genus appears to be related to the Kj-aemeriidae more than the 

 Microdesmidae. The key on p. 4 distinguishes it from related genera.
