 aUrichianua Wyville Thomson. See Science News Letter, vol. 60, No. 15, 

 October 13, J961, p. 227. 



^ Mortensen gives Tromikosoma hispidum from the Gulf of Mexico by error 

 tor the Qulf of California. 



' In the western part of the Oulf of Mexico this species is frequently circular, 

 and is then easily mistaken for a species of HeUocidaris. Verrill in 1867 

 recorded (?) Anthocidaris mezkana A. Ag. from Vera Cruz. In the reprint 

 of his article he says that Mr. Agassiz considers this his Echmometra plana 

 i = E. viTidis). It is probably* the circular variety of E. lucunter.
