If this is typical of wild fish in spawning condition, it indicates that spawning events are partial and sporadic or partial, with very few eggs fertilized at a time, and reproductive activity extends over a long period of time, perhaps throughout the year.

As elsewhere in the skeleton, stress on the vertebral column apparently results in significantly higher levels of calcification, which show up in radiographs as brightened areas. As usual in cyprinids, the anterior half of the centrum of each abdominal vertebra where it articulates with the ribs is particularly well mineralized (pers. obs.). Of more interest is that the centrum of the third post-abdominal vertebrae is often strongly calcified. This sample of

This new species is distinguishable from all other known species by its extraordinary colouration. Most of the body is deep blue, steely blue or greenish blue with numerous white, cream-coloured, pearly pink, or goldeniridescent oval spots. The dorsum, covered by the dorsomedian scale row and the first scale row immediately below it on either side, is bronze or greenish from the head to the end of the body. The ventrum, covered by the ventro-median scale row and one or two scale rows on either side of it, is rosy or reddish from the head to the end of the body. In males, the white-spotted bluish colour of the flanks covers the sides of the anterior part of the abdomen. In females, this part of the external body wall is white or cream. The dorsal, anal, and caudal fins in both sexes, and also the pelvic and to a lesser degree the pectoral fins of the males, have broad cinnabar red and black slashes. See Discussion for comparisons of colouration in other danioins.

Variation in the disposition of the spots, especially in somewhat smaller fish, indicates that they develop from (and therefore presumably evolved from) continuous or nearlycontinuous longitudinal pale stripes of the sort seen in many danioins. In some of these danioins, the longitudinal stripes occasionally break up into smaller units suggestive of the numerous small oval spots in
