(GARIBALDIS.) 

 Hypsypops, GILL, Proc. Ac. Nat. Sci. Pliila. 1861, 165 (rubicundus). 



Body very deep, covered with rather large ctenoid scales which extend 

 on the bases of the vertical fins; caudal peduncle short and deep; head 

 very deep, with prominent forehead and snout; 110 scales before nostrils 

 and none on lower limb of preopercle; preorbital very deep, but not so 

 deep as in Micro spathodon. Jaws subequal ; mouth small ; teeth all narrow, 

 fixed, entire, those below covering whole edge of the jaw; caudal emargi- 

 nate, Avith rounded lobes. One species of large size, its coloration chang- 

 ing with age. (vi^i, high ; vito, below ; 02^, eye, from the wide preorbital. ) 



1978. HYPSYPOPS RUBICUNDUS (Girard). 



(GARABALDI.) 



Head 3; depth If. D. XII, 16; A. II, 15; eye 4| in head; snout 2; 

 pectoral equals head ; highest dorsal spine 3 ; highest dorsal ray 1 ; sec- 

 ond anal spine 3; scales 5-30-13, 21 pores. Body short and deep, ele- 

 vated and compressed, constricted behind the dorsal and anal, the caudal 

 peduncle short and deep ; head higher than long, the preorbital and sub- 

 orbital regions being unusually deep ; preopercle entire ; cheeks, opercles, 

 and top of head scaly, except snout and lower jaw, which are naked; 

 mouth small; lips thick; teeth compressed, narrow, blunt, and entire, in 

 a single row, dark at tips; gill rakers short and flexible, about 3-J-12; 

 preorbital anteriorly as wide as the eye, about 4-J- in head in adult; cheeks 

 with 5 or 6 rows of rather small scales, opercles with several rows of larger 

 ones; preorbital with small crowded scales ; lips thick, the lower without 

 frenum ; soft fins rather high ; pectorals reaching to tip of ventrals, nearly 

 to vent. Adult uniform deep scarlet in life, unmarked, edges of fins 

 dusky. The color of the young of this species is quite variable, and dif- 

 ferent from that of the adult. The following account of the coloration of 

 the young is given by Miss Rosa Smith (now Mrs. C. H. Eigenmann) : 



" Hitherto only the adult form of this species has been known, and its 

 uniform deep scarlet coloration has been considered to form a marked con- 

 trast to the coloration of the other species of Pomacentrus. I have lately 

 secured numerous young specimens, and find their coloration quite differ- 

 ent from that of the ad alt, and in general similar to that of the other 

 members of this genus. 



"The ground color is dusky scarlet, with numerous markings of an 

 intensely bright blue, which occasionally changes to bluish green. Two 

 series of elongate spots form a blue stripe on either side of the median 

 line, between tip of snout and beginning of dorsal fin; a line of blue on 

 superior margin of iris is followed posteriorly by an irregular series of 

 blue spots above the lateral line (the individual spots not quite equaling 

 diameter of iris), the last of these spots is larger than those which precede 

 it, being of the orbital diameter, and extends up to the base of the 

 dorsal fin at the posterior third of the spinous portion; thence very
