Localities. — Off the coast of Ceylon, 32-34 fathoms (Indian Marine

 ^larine vSurvey).

Fig. di.— Reteporella'^ sp. 



Zoarium branched, surface glistening, zooecia smooth, with large 

 pores here and there round the margin. The front wall rising from 

 the base upwards to rather prominent shoulder-like projections on 

 either side of the orifice. Primary orifice with two teeth near the 

 base, sometimes meeting and leaving a pore below them. Secondarj' 

 orifice with a much raised peristome, cleft in front. A large avi- 

 cularium ending in two points, raised on an eminence and lying 

 across the front of some zooecia. 

 Locality. — Off west coast, Andamans, 290-238 fathoms (Carpenter). 



There is a general resemblance between this species and Smitt's 

 {^' Floridan Bryozoa," pt. ii, p. 67) Retepora marsupiata, but the 

 fragment in the present collection indicates a branched, possibly a 

 reticulate zoarium but not fenestrated, and the characters of the 

 primary orifice and of the avicularia do not agree with those of that 

 species.
