410 ME. G. A. BOULENGEE ON A COLLECTION OF PISHES 



oil-green below, with a vertical brown bar at the base of each scale ; the dorsal and 

 ventral are represented as dark sage-green, with round yellowish-brown spots, the 

 edge of the former and the corners of the latter crimson-red ; the pectoral lake-red, 

 the anal pink, edged with reddish and with round pinkish-white spots ; the ventral 

 olive-green. The second differs in having a blackish lateral stripe, extending from the 

 opercular spot to the root of the caudal fin. The third has also a lateral stripe, 

 but it is traversed by eight blackish vertical bars descending from the dorsal; round 

 white spots (in spirit) are very distinct on the anal. The largest specimen measures 

 210 mm. 



16. Paeatilapia SMiTHii Casteln. (Plate XXXIX. fig. 2.) 

 The original description of Chromys smithii (p. 16) is as follows: — 

 " Longueur totale, m. 23. — Corps assez eleve. Pectorales non-prolongees ; ecailles 

 au nombre de 22 sur la portion superieure de la ligne laterale, et de 14 sur I'inferieure ; 

 ces ecailles sont lisses sur le bord externe, avec le disque convert de granulations, 

 fermant un pen des lignes concentriques. Dents petites, sur deux rangees. D'un noir 

 brillant en dessus ; au dessous de la tete, d'un rouge fonce ; ventre jaune ; la dorsale 

 verdatre avec les pointes grises ; les ventrales et anale violettes ; les pectorales d'un 

 violet clair ; la caudale verdatre avec les pointes violettes." 



This species is regarded as near Chr.frederici, and confounded with it by the natives 

 under the name of Tapic. I have decided to refer to it three examples of aa 

 apparently distinct species, which I will describe under the above name.
