region. Gill apertures continuous under the throat, gill membrane free 

 from isthmus, liranchiostegals 6. Mouth moderate, the contour of the 

 upper jaw semicircular; upper jaw protruding beyond the lower; lips 

 moderate, uniform and free, concealing the teeth. Teeth labial and mov- 

 able, very slender and recurved, contiguous and uniserial; no posterior 

 canines. Dorsal fin divided ; anal similar to soft dorsal ; caudal obtusely 

 rounded; pectorals moderate, angularly rounded; veutrals approximated, 

 each with 3 simple rays, the internal of which is smallest. This genus is 

 very close to the Old World genus, Salavxas* Cuvier, which differs in 

 having the dorsal tin continuous, as in BiqnscarUs. {dudpriji;, one who

2747. SCARTICHTHVS RUBROPOCTATUS (Cuvier & Valencienues). 



Head 4; depth 4 (5 with caudal); D. XI-16; A. 20; eye 4* in head; 

 teeth less flexible than in Bupiscartcs atlanticus ; no canine teeth ; the fore- 

 head not projecting beyond the mouth; a very small tentacle on the neck, 

 a longer fringed one above the orbit ; dorsal tin deeply notched, not extend- 

 ing on to the caudal. Color brown, niarbled with black, and dotted with 

 reddish ; a black spot on the anterior part of the dorsal ; throat with 2 or 3 

 brownish cross bands; a jet-black spot behind eye, with a narrow edge 

 posteriorly. (Giinther.) Coast of Peru and Chile, north to Panama.

 Islands, near Panama, and at Callao. Length 3 inches, (rube?-, red;

This genus, as here understood, differs from Salarias only in the presence 

 in 1 or both jaws of posterior canines. Dorsal fin continuous, without deep 

 notch. Vertebrie 12 -f 22^34 {atUmiicHS). (nqics, rock; 6HdpT}is, one 

 who leaps; Kitpiscarfes tridacti/lm (aUictis), "said to jump on the sea rocks 

 like a lizard." Swainson.)

t We do not think that the name Alticus can be substituted for Rupiscartes. because 

 LacL*i)ede does not adopt this genus of Commerson, but merges it in Jileiiiiiiis. (|uoting 

 Comnierson's account as a footnote. This is as follows: "Alticus saltatoi-itis, pinna siiuria 

 in capitis vertice ; sen pinnula longitudinali pone oculos cartilaginea ; seu alticus desultor, 

 oeci]>it(' cristato, ore circulare deorsum patulo." Apparently this quotation of a generic 

 des(iii)ti(in not approved, does not give priority to the latter. 



I This gi-uus Alticus is not adopted by Cuvier & Valenciennes. Valenciennes speaks 

 of "un petit Salarias que nous parait etre' celui-la mcme sur lequel Commerson avait^tabli 

 son genre Alticus." But a genus is not established until it is accepted by some authority 

 as well as defined.
