39. Lagenipora socialis, Hincks. 



Ann. Mag. Nat. Hist., series 4, vol. xx, p. 215, 1877. 



The colonies of this species are in the form of little caps which 

 appear to have encrusted some round body and from which they are 

 broken off. The zooecia radiate from a hole in the centre which is 

 occupied in some cases by the stem of a branching red coral. The 

 tubular orifice of the zooecium has often spinous processes behind. 

 The specimens differ from Hinck's description in having a roughened 

 instead of a smooth wall to the ocecia, and in having perforations 

 scattered over the whole front wall of the zooecium. 

 Locality. — Andamans .

41. Monoporella albicans, Hincks. 



Ann. Mag. Nat. Hist., series 5, vol. ix, p. 123, 1882. 



There is a purplish tinge to these colonies, caused by the dark 

 colour of the operculae as in Cellepora alhirostris (Smitt ' ' Floridan 

 Bryozoa," pt. ii, p. 70, in Vetensk. Akad. HandL, vol. xi, 1872). 

 Locality. — Marshall Channel, Andamans (Indian Marine Survey).
