maxillary 2.3 to 2.6; interorbital space 3.4 to 3.0; second dorsal 

 spine 1.4; pectoral 1 ; ventral 1.2. 



Snout moderately emarginate, the lateral prominences short and 

 sharp, consisting typically of a single spine on each side, or (in adults) 

 of a single prominence (or two) longer than the rest; preocular spines 

 very small, nearly obsolete; nuchal spine reaching past base of second 

 dorsal spine; opercular spine extending on anterior fifth of base of 

 humeral spine ; humeral spine long and sharp, reaching nearly to 

 base of filth dorsal spine; second dorsal spine but little (about one- 

 eighth) longer than third and very weakly serrated, being as a rule 

 smooth for the outer fourth of its anterior edge; pectoral to vertical 

 from fifth ray of soft dorsal; u})per detached pectoral ray short, 

 missing the tip of the ventral by a distance about equal to diameter 

 of eye; dorsal scutes moderatel}^ developed, their spines short and 

 not very sharp. 



Life color, bright brick red above, the belly abruptly white, the 

 junction marked by a silver line; fins red, or with some cream}' 

 white; a black blotch on the spinous dorsal between the fourth and 

 seventh spines; no blue. In preserved material the dorsal blotch 

 shows most plainly in young specimens (vmder 4 inches). In adults 

 it is sometimes almost wholly wanting." 



This species differs plainly from both L. gilntheri and X. ahyssalis 

 in its shorter detached pectoral rays and in the presence of the 

 (usually) prominent tiark blotch between fourth and seventh spines 

 of first dorsal. There appears to be no doubt that L. smithii Regan 

 is the young of this species. Young specimens in our collections 

 from Nagasaki and Wakanoura have D. VIII-15 and A. 15. In one 

 of these the first (rudimentary) anal ray is but three-eighths of the 

 second, and the second only two-thirds of the third. Regan's figure 

 shows the first spine fully five-sixths of the second, a condition we 

 have not observed in any specimen. As his specimens were all small 

 (7 to 9 cm.) it seems not impossible that he may have overlooked a 

 rudimentary spine. The dark longitudinal bar on the soft dorsal, 

 described by Regan, is a characteristic of young specimens, appearing 

 in two 3"Oung individuals 4§ inches long in our collection from Aomori.

 as L. strauchii.
