Even in the anal spines the second maTbe equal m length to the third or a little longer or shorter in the same species. As regards colour the youn™ generaUy vertically banded and these bands may be indistinct or even entirely absint in the adult. In those with longitudinal bands they sometimes become interrupted in large specimens, showing rows of long oval blotches or marks placed one oyer the other, the reason usually being that these marks are apparent in the adult where the vertical bands existed m the immature.
