The geographical distribution of lleliaster is fully discussed in this paper 

 on p. 8, 11, 75, 76, 98-100. By a curious slip of the pen on p. 43, lleliaster 

 is said to be peculiar to " le cote orientale " of America, and the same slip 

 is repeated with reference to Pycnopodia.

This very important paper deals fully (p. 61, 63, 93, 99, 111-116) with 

 the skeletal anatomy of Heliaster, and discusses its relationship with other 

 starfishes. On plate 6 are given some structural details (figs. 4-12). The 

 conclusion is reached that the peculiarities of Heliaster are sufficient to 

 warrant its elevation to family rank, as the Heliasteridae.

The family Heliasteridae is recognized in this work, although the refer- 

 ences to it (p. 139, 143, 153, 154) and to the type genus are unimportant.

On p. 160 the genus Heliaster (apparently under the " Asteridae") is 

 referred to as having two species, kubiniji and microbrachia, on the west 

 coast of North America from Panama to Cape St. Lucas.

On p. 934 Heliaster Gray is given as a genus of Asteriadae, with 

 " mehrere Arten," but helianthus (Lam.) Gray is the only one mentioned.

In this, the most important paper published dealing with the taxonomy 

 of Heliaster, four species are clearly distinguished, fully described, and ad- 

 mirably figured. The writer considers H. kubiniji Xantus (which is spelt
