and may be recognized readily by 3 horizontal rows of scales on the 

 cheek and preopercle, with a horizontal groove extending from the 

 upper jaw to the opercle below the upper row of scales, and the 

 presence of scales on the upper part of the opercle, together with a 

 pal© brown body marked by a median longitudinal series of dark 

 spots, terminating at the base of the caudal fin in a conspicuous round 

 black spot and a dusky caudal fin set off with 4 or 5 transverse lines 

 or rows of white spots. 



The peculiar squamation of the cheek, with the deep horizontal 

 sulcus, differs from the normal squamation of the cheek as seen in 

 what may be considered typical Gnatliolepls^ exemplified by the 

 species deltoides of Guam and the Philippines, and may, with several 

 other characters, justify the establishing of a new genus for the 

 accommodation of caUiuj'^u^s. 



AULOPAREIA, new genus 



Genotype. — Aulopareia ja7ietae, new species. 



Bod}^ elongate, moderately compressed ; head cylindrical ; eyes small, 

 dorsal lateral, in anterior third of head, separated by a rather wide 

 space ; mouth rather large, oblique, lower jaw slightly projecting ; teeth 

 pluriserial, outer row in upper jaw comprising 8 fanglike canines, 

 outer row in lower jaw somewhat enlarged, the last tooth on each 

 side a large, recurved canine ; tongue with rounded tip ; gill openings 

 of moderate extension forward; body, including preclorsal region, 

 breast, and base of pectoral fins, completely covered with rather large 

 ctenoid scales becoming cycloid anteriorly; top of head scaled, the 

 scales extending throughout interorbital space to a point nearly in 

 line with the anterior margin of each eye ; no obvious pores in inter- 

 orbital space; opercle, preopercle, and cheek fully scaled, the scales 

 on cheek extending as far forward as anterior edge of eye and ar- 

 ranged in G horizontal rows separated by narrow grooves or f urroAvs ; 

 dorsal rays VI-1, 10 ; anal rays I, 9 ; caudal fin short, bluntly pointed. 



In having the opercle, preopercles, cheeks, and top of head densely 

 scaled this genus resembles Gnatholepsis ; but in the extension of the 

 scales throughout the interorbital space, in having the numerous hori- 

 zontal rows of scales on the cheeks separated by four horizontal 

 grooves, in the cylindrical head with wide interorbital space, and in 

 various other characters, this genus stands apart. There is rather 

 close similarity to Exyrias^ with the type species of which genus, 

 Gohhis puntang Bleeker, it has been compared, but in that form the 

 head is compressed, the interorbital space is narrow (0.5 eye or less), 

 with a pair of conspicuous pores, the posterior nostril is well sepa- 

 rated from the eye, and scales extend only to the posterior half of 

 the interorbital space.
