that none of these characters are constantly joined with a second, and 

 that such variations occur in specimens caught together at the same 

 locality and otherwise quite identical. One «f the most singular 

 varieties is the specimen h, from Cannes, with 4| longitudinal series 

 of scales above the lateral line. Specimen c, procured by my brother 

 at the same time and at the same place, has the scales above the 

 lateral line as large as in the other specimens; and there can be scarcely 

 any doubt that both are specifically identical. The colours are given 

 below. 



a. Colours of specimen n. (male), seven incites long. — Pectoral yel- 

 low ; a blackish blotch above the pectoral. Green, each scale with 

 a bluish spot ; three red longitudinal bands : one on the back, along 

 the base of the dorsal fin, the second immediately above the lateral 

 line and along the back of the tail, the third along and below the 

 caudal portion of the lateral line; snout violet; numerous bright-red 

 dots behind the eye. The spinous dorsal dark- violet, with a series of 

 red spots, a blue intramarginal line and a red margin ; the soft 

 dorsal and the anal green below and reddish above, with many blue 

 ocelli. The caudal and ventral red at the base and yellow in their 

 outer half, with numerous blue ocelli. 



b. Colours of specimen h, from Cannes. — Pectoral transparent ; a 

 blackish blotch above the pectoral, another smaller one at the root 

 of the caudal below the end of the lateral line. Reddish -olive 

 above and on the sides, silvery below ; a light shining silvery band 

 runs from the eye to the middle of the caudal, and is bordered by 

 two purplish bands — the upper along the anterior portion of the 

 lateral Kne and the back of the tail ; three series of large blackish 

 blotches on the sides. The soft portions of the vertical fins with 

 small ocelli in moderate number.
