PAXAMIC DEEP SKA ECHINI. 



In a specimen of 13 mm. (Pis. 17, figs. /, 2; 18, figs. 3, '/) the seventh 

 pairs of intern mbulacral plates are fully developed in all the areas except 

 the left anterior, and the eighth pair is indicated in two of the interam- 

 bulacra, Fig. 85. The first pairs of actinal interambulacral plates are still 

 in contact with the actinal system, lint of course they have become greatly 

 reduced in size from the early stages examined (PI. 16, figs. J, ,.') when the 



13 ram.

first actinal interambulacral plates were of full size. The first ambulacra! 

 plates not flowing continuously, but having only a most limited resorption, 

 are only gradually somewhat reduced in size in the successive stages of growth. 

 This species is, like most Saleniai I have seen alive, brilliantly colored, 

 though not as strikingly as S. Paitersoni. In S. miliaris the papillae of the 

 test are a dark violet, while the primary radicles are a brilliant white 

 enamel. On the apical system the sessile verruca? are light claret color.
