CLARK: THE STARFISHES OF THE GENUS HELIASTER. 31 



On p. 289-293 are good descriptions of Heliaster helianthus, microbrachia, 

 Cumingii and Kubiniji, with special attention given the pedicellariae. The 

 description of Kubiniji, which is considered distinct from multirudiata 

 Gray, is based on a specimen "obtained at the Sandwich Islands. It prob- 

 ably came from Acapulco or Mazatlan." This specimen is of interest 

 chiefly because, through a mistake of Perrier's, it is the source of all 

 Hawaiian records.

The geographical distribution of the genus Heliaster and of H. Cumingii, 

 helianthus, Kubiniji, microbrachia, and multiradiata, is referred to on p. 328, 

 329, 331, 333-335, 344, and 348.

On p. 202-203 Heliaster is recognized as a good genus, but on p. 231 the 

 writer decides it is not valid. A description of the pedicellariae of Aster- 

 acanthion and Heliaster occupies p. 202 219 and on plate 7 is a figure (16) 

 of a forcipiform pedicellaria of Asteracanthion helianthus. On p. 203 it is 

 stated: "Dans toutes les especes appartenant aux genres Asteracanthion 

 et Heliaster on trouve deux sortes de Pe'dicellaires, nous designerons . . . 

 l'une . . . Pe'dicellaires droits, l'autre . . . Pe'dicellaires croise's." But on 

 p. 231 under Heliaster helianthus, the writer says, " Nous ne connaissons pas 

 encore les pe'dicellaires droits " !
