54 - Records of the Indian Museum. [Vol. XXII, 



Most of the zooecia possess the avicularium just below the sinus. 

 This is lacking in other instances but replaced apparently by 

 anotUer avicularium, somewhat larger usually, but placed some- 

 where else on the front wall, most generally on the lower part 

 with mandible directed transversely. Occasionally both kinds of 

 aviculiaria are found on the same zooecium.

Schizoporella biaperia. Hincks. iSSo, p. 255, pi. xl, fisf?. 7-9. 



Obtained at two stations at the Andamans. 



Slight variations occur in these specimens differing from 

 those described by Hincks. The ooecia possess twp transparent 

 areas on the front instead of an area with radiating lines. The 

 mammillated avicularia possess a spatulated mandible, not a 

 triangular one, as does the British species.
