SCI^NA PERISSA sp. nov. 



Type. — Cat. No. 6360 Leland Stanford Jr. University Museum. 

 Tagus Cove, Albemarle Island. 



Diagnosis. — Distinguishable from any other member of the genus 

 by the weakly serrated preopercle, enlarged anal spine and the small 

 number of spines in the dorsal. 



Description of the Type. — Length 1S3 mm. ; depth two and three 

 fifths ; head about three ; upper profile of body strongly convex, 

 greatest depth at front of soft dorsal ; ventral profile much less con- 

 vex, evenly rounded; snout blunt, rounded; lower jaw included, sym- 

 physis nearer vertical from anterior nostril than from point midway 

 between anterior nostril and snout. Tip of snout slightly lower than 

 anterior nostril, strongly receding to mouth; mouth nearly horizontal ; 

 profile from snout to nape almost straight. Snout below tip with eight 

 pores, a large slit-like pore on each side, three just above mouth, three 

 very small ones just above these ; symphysis with five pores, one 

 small, slit-like, median one, two on each side, of which the posterior is 

 the larger. Teeth small, in bands along sides of jaws, the outer ones, 

 especially in upper jaw, enlarged ; bands in lower jaw wide in front, 

 tapering posteriorly ; no vomerine teeth. Anterior nostril lower and 

 smaller than posterior. Suborbital a little narrower than vertical 

 diameter of eye. Ascending limb of preopercle very weakly serrated, 

 inclined forward ; space between its upper end and orbit equal to 

 vertical diameter of eye. Opercle with wide meinbranous flap on 

 posterior border above angle.
