22 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY III. 



Eye moderate, less than snout, 1 in head. Mouth rather small, <iuite 

 oblique, the maxilhir^' not attaining the line of the orbit, the upper Jaw 

 l)rojecting beyond the lower, especially in spring males. The head and 

 mouth considerably resemble those parts in P. <inalostani(s. 



Scales much deeper than long, very closely and smoothly imbricated, 

 more or less dark-edged above. 5-37-3. Lateral line decurved. 



Fins moderately developed : dorsal distinctly behind veutrals, its first 

 ray about midway between nostrils and the base of the caudal. Dorsal 

 1,8. Aiml 1, 8. 



Nuptial tubercles in the male greatly developed, covering rather 

 sparsely the top of the head and the region anterior to the dorsal. In 

 addition, similar tubercles cover the caudal peduncle and the whole sides 

 of the body, except the space below the lateral line and in front of the 

 ventrals. The tubercles ou the body are considerably smaller than 

 those on the head, and smaller than in xamtra or jijjrrhomclas, but they 

 cover a much larger area than iri any of the latter species of the geuus. 

 Chin tuberculate. 



Teeth 1, 4-4, 1, entire, without masticatory surface. 



Coloration, in life: General color a dark steel blue, a very distinct 

 blue stripe along each side of the caudal peduncle, as in C. cccnilca, but 

 fainter : sides of body with tine steely-purple lustre: back clear green : 

 head clear brownish : iris white: cheeks of a pale violet color : lowor 

 part of sides becoming rather abruptly n)ilky-white: dorsal fin with 

 the usual large black spot ou the last rays well developed, and the 

 usual milk-white pigment in the tips: lower part of the <lorsal fin with 

 l)igment of a fine clear green color, somewhat as in analostanus, but 

 unusually bright: cjiudal fin chiefiy dusky, its tips milky and the base 

 somewhat so; the middle of the fin has a slight reddish tinge: anal 

 tin entirely milky, a faint dusky spot ou its last rays, resembling that 

 on the dorsal : ventral fnis milky. 



Female and young specimens are more slender, and the bright colors 

 are usually wanting or obscured. 



8ize small ; length of largest specimens less than three inches. 



In fortn, this s|)ecies resembles C. pyrrhomclas, but the short anal 

 (eight rays instead of ten) will always distiuguish the species. The 

 cDloration of the male is dilTerent, being much less brilliant, although 

 l»erhaps more delicate. C. chlori.stia resembles in color C.cixndca most, 

 but the latter species has a much more slender form. 



Habitat. — Abundant in the clear waters of Saluda River, with C.
