(Garibaldis.) 



"Eypsypops, Gill, Proc. Ac. Nat. Sci. Phila. 1861, 165 (ruhicv.ndus) . 



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

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

 very deep, with i>romincnt forehead and sn(nit; no scales before nostrils 

 and none on lower limb of jireopercle; preorl)ital very deep, hut not so 

 deep as in Microspathodon. Jaws suljetiual ; nu)uth small ; teeth all narrow, 

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

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

 ing with age. (vrfti, high ; VTto, below ; Sip, eye, from the wide preorbital. ) 



1978. HVPSYI'Ol'S RIBUUNDUS (Giiard). 

 (Garadaldi.) 



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

 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, o])ercle8, 

 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+12; 

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

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

 ones; preorbital witli 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 Eosa Smith (now Mrs. C. H. Eigenmann) : 



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

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

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

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

 ent from that of the adult, 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 clianges to bluish green. Two 

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

 line, between tip of suout and beginning of dorsal fin; aline 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 J of the orbital diameter, and extends up to the base of the 

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