Body covered with minute, somewhat embedded scales. 



Color in alcohol. — A black streak along middle of side, one along 

 middorsal line of back, and one along middle of length of dorsal fin 

 rays. 



Remarks. — Kendall and Goldsborough described Paragobioides 

 grandoculis and referred it to the Gobiidae. Their description is 

 inadequate and their figure 2 is in error regarding the origin of the 

 dorsal fin. The latter has its origin in front of middle of length of 

 pectoral fin, not behind tip of pectoral as shown by Kendall and 

 Goldsborough. J. L. B. Smith described P. copleyi as new, separating 

 it from P. grandoculis on the supposed origin of dorsal behind tip of 

 pectoral, a character that does not exist on the holotype, USNM 65975. 



Bleeker described Gunnellichthys pleurotaenia from Menado in the 

 Celebes Sea as new. I have examined two of Bleeker's specimens, 

 loaned from the Leiden Museum, No. 4799, and cannot detect any 

 differences between them and the other specimens before me from the 

 tropical Pacific. Later de Beaufort in de Beaufort and Chapman 

 figured Bleeker's G. pleurotaenia. Color pattern, counts, and other 

 details are the same as in P. grandoculis, and I conclude that the 

 latter is a synonym of G. pleurotaenia. 



ALLOMICRODESMUS, new genus 



Type species. — Allomicrodesmus dorotheae, new species. 



This new genus is characterized by having the dorsal and anal fins 

 free from the caudal; gill openings not restricted to the side of head 

 but with a free fold of the branchiostegal membranes across the 

 isthmus; body naked, no lateral line; lower jaw longest, swollen at the 

 tip; tongue simple at tip; eyes large, lateral in position; inner pelvic 

 rays longest; air bladder probably present. 



This genus appears to be related to the Krameriidae and to the 

 Microdesmidae. The key on page 4 distinguishes it from the other 

 genera referred to those families.
