all the above-mentioned accounts. It is possible that three or ibiir 

 six^cies of this type exist, but our knowledge of the variations in /*. 

 hivittatus leads us to doubt this, and to regard all as one. Pluti/glon.sus 

 pictus seems the most different from our examples of any of these nom- 

 inal species. 



AVe have rejected the name crotajjhus, because in the Regnc Animal, 

 where the name first appears, it is accompanied only by a reference to 

 the Doncella of Parra, which is P. radiatus. 



Genus 2. OXYJULIS. 



Oxyjulis Gill, Proc. Ac. Nat. Sci. Phila., 18G3, 330 (modesius). 



This group is intermediate between Platyglossus and Fseudojulis, dif- 

 fering from either only in trifling respects. The single known species 

 is very slender, with very feeble dorsal spines, and with the posterior 

 canine chiXTacteristic of Plafyglossiis either represented by a small rudi- 

 ment or else altogether wanting. Occasionally but eight dorsal si)ines 

 are present, as in Thalassoma. The genus seems, however, to be as well 

 worthy of retention as many others among the Lahridce. 



ANALYSIS OF SPECIES OF OXYJULIS. 



a. Body elongate, strongly compressed, the back not elevated, the head sli uder and 

 sharp ; depth, A\ in length of body; snout 3 in head ; eye 5 ; posterior canine 

 weak or wanting, rarely present on both sides; scales before dorsal much re- 

 duced, in 10 to 12 rows, those on breast considerablj' smaller than those on 

 sides ; caudal truncate ; ventrals short, the first ray not twice the length of the 

 inner ray ; dorsal spines flexible ; olive-brown; centers of scales orange-brown ; 

 belly cream color; sides of head with alternate streaks of bluish and brown ; a 

 large inky blotch at base of caudal, covering one-third the fin ; membrane of 

 base of spinous dt>r8al largely indigo-blue ; fins otherwise pale ; lower pharyn- 

 geals formed as usual in Piatyglossus, the large teeth less obtuse.
