30 NEW INVERTEBKATA FROM 



mseous. When expantled, their tips extend about double 

 the diameter of the l)ody. Radial lines of the septa, on 

 the perioral region, appear as silvery, donl)le lines, ex- 

 tending from the mouth to the tentacles. Small simple 

 mouth, with slightly raised perioral prominence. Mouth 

 has the form of a longitudinal slit. Body adherent, ten- 

 tacles wholly retractile. Si)hincter muscle strong. The 

 eenus lives in colonies covering rocks which are bare at 

 low tide. Whole colonies are hidden by coating of small 

 shells and gravel, and seem to retain considerable water 

 from one tide to another in their body walls. 



Found abundantly on the rocks at Point Castillo. Mag- 

 nificent specimens of this Bunodes, ten inches in diameter, 

 were found on the island of Santa Cruz. The tentacles 

 are a beautiful green and yellow color. In these speci- 

 mens the tubercles situated about the ring of tentacles 

 formed a thickl}' crowded zone on the body, and have a 

 dull yellowish or brownish color. Like the specimens 

 from the rocks of Punta del Castillo these Bunodes like- 

 wise collect foreign bodies upon the knobs, but in places 

 where there is little sand these aggregations are for the 

 most part pieces of shells and fragments of seaweeds. 



Large numbers of the young of all sizes occur at the 

 bases of the older specimens, and evidences of fission can 

 be readily seen. That the colony is formed in that way and 

 by gemmation from the base seems to be doul)tless true.^ 



iM. Nussbaiim gives a very short account of fission in an unknown Actinia from 

 the coast of California. Tliis may i)ossibly be the same genus as that which 1 

 call Bunodes, but tliere is notliing to jirove that such is the case as his notice is so 

 imperfect that the animal stuilied caniot be identified. I have often taken Bu- 

 nodes with young clustered at the base, and tlie form of tliecolony would indicate 

 that this mode of reprodiu;tion is very common. (See Nussbaum, Vorliiufiger
