similar to second dorsal, the rays 1,8; ventrals equal to pectorals and, 

 extending more than half distance to anal ; pectorals broad, rounded, 

 as long as postorbital part of head. 



Life colors : Body and head pale yellow ; five irregular reddish- 

 Ibrown cross-bands meeting on back and reaching more than half dis- 

 tance to median ventral line, one band on nape extending on base of 

 pectoral, one band under spinous dorsal, two bands under second 

 dorsal, and one band with a straight posterior edge extending 

 entirely across caudal peduncle and base of caudal fin ; a dusky area 

 on top of head behind ej^es, extending to preopercle ; fins hyaline, the 

 three bands under the dorsal fins extending faintly on their bases. 



Type. — A speciman 2.6 cm. long, taken on Koh Pipidon, west coast 

 of Siam, March 10, 1925. Cat. No. 90317, U.S.N.M. 



Remarks. — The only known specimen of this fish was obtained in a 

 tide-pool on the small island of Pipidon, on the west coast of Penin- 

 sular Siam, south of Puket. It is strikingly marked and is easily 

 recognized notwithstanding its small size. 



HERREA, new genus 



Size minute; body elongate, compressed, scaleless; head blunt, 

 mouth vertical ; teeth in each jaw curved, in a single wide-spaced row ; 

 anterior teeth in lower jaw elongated; dorsal fins widely separated, 

 the first dorsal with 5 spines, the second dorsal and the anal with 12 

 branched rays ; caudal rounded ; ventrals narrow, pointed, not adnata 

 to abdomen. 



Resembles Mirogobius., dascribed by Herre from the Philippine 

 Islands, in being scaleless and in having a single row of teeth in both 

 jaws, but that genus has postsymphysial canine teeth in lower jaw 

 and only 7 to 9 branched rays in the second dorsal, together with a 

 reduced number of anal rays. 



This genus is named for Dr. Albert W. Herre, formerly of the Phil- 

 ippine Bureau of Science, in appreciation of his invaluable mono- 

 graph Gobies of the Philippines and the China Sea (Manila, 1927). 



HERREA FORMOSA, new species 



Description. — Slender, compressed, dorsal profile nearly horizontal ; 

 depth contained 6 times in length; head 4.5 in length; snout blunt, 

 0.5 eye; eye large, more than 3 in head and greater than interorbital 

 space; mouth vertical, a single row of curved, wide-spaced teeth in 

 each jaw, with longer anterior teeth in lower jaw; depth of caudal 

 peduncle 1.5 in its length ; no scales on head or body. 



Fins : Dorsal rays V-I,12 ; first dorsal separated from second dor- 

 sal by a space 1.5 times length of first dorsal base, spines weak, third 

 spine longest; origin of second dorsal somewhat in advance of that 

 of anal, longest rays equal to postorbital part of head, the base 3.5 

 times that of first dorsal, last ray just reaching caudal; caudal
