The new genera and species of starfishes described in this paper were 

 obtained from among the Philippine Islands and the neighboring 

 islands to the southward by the steamer Albatross during her cruise 

 of 1907-1910. These species will be fully illustrated and described 

 in greater detail in the final report on the collection. 



In two previous papers ^ 10 new genera, one new subgenus, and 64 

 new species were described. 



In the present paper the following new genera are characterized: 



Halityle (Oreasteridse, near Culcita). 



Dissogenes (Linckiidse, aberrant). 



Tarachaster (Ganerudas, aberrant). 



A new subgenus of RUpidaster, Xenorias, founded on a new species, 

 Rhipidaster polijctenius, is described. 



A list of the new species and subspecies is given for ready reference.
