Text Figure No. 95. Spicules of Anaata lajorei, X 782. A: Style; the entire spicule is 



shown, but in two parts. B : Intermediate type, between A and C. C: Echinating acan- 



thostyle. D: Two of the arcuate isochelas ; one front view, one in side view. 



The species lajorei is set off quite sharply by its black color ; furthermore, 

 most species in Anaata have tylostyles in addition to the styles. The genus 

 is very close to Wilsonella, but typical Wilsonella species also have diacts or 

 quasidiacts. 



The specific name here selected is given in respect to the native chieftain 

 of the atoll called Ailing-lap-lap.
