Holotype.—A specimen (U.S.N.M. No. 116169) 12.2 mm. in stand- 

 ard length collected by Leonard P. Schultz on the reef of Rose Island, 

 June 11-14, 1939 along with five paratypes (U.S.N.M. No. 116170), 

 bearing same data, 12 to 14.1 mm. in standard length. 



Description. — (Based on the holotype and five paratypes listed 

 above. The measurements and counts for the holotype are given out- 

 side the parentheses and those for the paratypes in the parentheses. 

 All measurements recorded in hundredths of the standard length, 



12.2 (14.1; 14.1; 14.1) mm.) Greatest depth 19.7 (17.0; 19.9; 17.7); 

 length of head 29.5 (29.0; 27.8; 29.0) ; diameter of eye 9.8 (12.0; 10.6; 

 10.6) ; tip of snout to posterior corner of maxillary 12.3 (13.4 12.7 

 12.0) ; length of snout 4.9 (5.7; 5.7; 5.7;) ; postorbital length of head 

 i.4.7 (14.2; 14.2; 14.2); snout to origin of spiny dorsal 35.2 (39.0; 

 36.2; 36.2) ; snout to origin of anal 57.3 (57.4; 57.4; 55.0) ; length of 

 caudal peduncle or distance from base of last anal ray to base mid- 

 caudal fin rays 24.6 (20.9; 24.8; 29.8) ; least depth of caudal peduncle 



12.3 (10.6; 12.0; 11.3); length of longest pelvic fin ray 24.0 (27.0; 

 -; -;); length of caudal fin 23.8 (-; 23.3; 22.6); length of longest 

 pectoral fin ray 21.3 (27.0; -; -;). 



Dorsal rays Vl-I, 9 ( VI-I, 9 ; VI-1, 10 ; VI-I, 9 ; VI-I. 9 ; VI-I, 9) ; 

 anal rays I, 9; (I, 8; I, 8; I, 8; I, 9; I, 9; I, 8) ; pectoral rays 17 

 (17; 18; 17; -; -;) ; pelvic fin rays I, 4, with the fifth rays absent 

 or rudmentary. Scales have been mostly lost on all the types but 

 there are about 26 or 27 scale rows from gill opening to base of caudal 

 fin and 8 scales in the transverse row from origin of second dorsal 

 to anal fin base.
