623. NEXILARIUS, Gilbert. 



Xexilarius, GILBERT, in JORDAN &. EVERMANN, Check-List, 512, 1896 (concolor) ; misprinted 

 Nexilaris. 



This genus is very close to Abudefduf and especially to the section called 

 EuxcMstodux, from which it (lifters in having the broad suborbitals entirely 

 adnate to the cheeks, as in Lepidozygus, and covered by scales so that the 

 outlines can not be traced without dissection. One species known, (nex- 

 Ui8j bound down.) 



1972. NEXILARIUS CONCOLOR (Gill). 



I lead 3^; depth If. D. XIII, 12; A. II, 10; scales 4-26-10, 21 pores. 

 Body broadly ovate, the anterior profile forming a steep and nearly even 

 curve from the snout to front of dorsal ; interorbital space convex, rather 

 broader than eye, which is 3^ in head; snout 3 in head; preorbital broad, 

 not notched, its least depth at angle of mouth 5 in head, its greatest ver- 

 tical depth 5; suborbital broad, completely covered by scales, its edge 

 not free and to be ascertained only by dissection; lower lip with a broad 

 free margin without median frenimi; teeth rather broad, deeply notched; 

 preopercle entire, with a shallow concavity behind; dorsal spines rather 

 low, the fifth highest, 2 in head ; soft dorsal and anal moderately elevated ; 

 upper lobe of caudal longest and broadest; pectorals as long as head; 

 ventrals a little longer, filamentous at tip. Color dusky olive, nearly 

 plain, with traces of 6 broad dusky cross shades corresponding to those 

 in Abudefduf declirifrons but much fainter; some faint olive streaks along 

 the rows of scales ; fins all largely dusky ; a black spot, broadest above, 

 growing narrow below, on upper half of base of pectoral; breast some- 

 times with dark streaks. Length 8 inches. Pacific coast of Central 

 America, rather common. Here described from specimens taken by Dr. 

 Gilbert at Panama. The species strongly resembles Abudefduf declivifrons, 

 but has the preorbital decidedly broader, the dorsal spines lower, the 

 black cross bands much fainter, the interorbital space more convex, the 

 anterior profile more evenly rounded, the snout shorter and lower, besides 

 the generic character of the adnate preorbital. (concolor, uniformly 

 colored.)
