Family Myriozoid^. 



43. Schizoporella tenuis, Busk. 



Voy. H.M.S. " Challenger," pt. xxx (vol. x), p. 165. 



The present specimens must be much finer colonies than those 

 described by Busk. The zoarium u free, forming hollow tubular 

 branches which expand into funnel-shaped ends whose sides some- 

 times fall in, forming various convolutions, and as growth proceeds 

 the branches meet and unite so as to make a confused^ interlaced col- 

 ony. These colonies are of very delicate texture and pearly white in 

 early stages of growth, becoming more substantial and of a shiny, 

 pinkish colour with age. Ooecia are present very large, each nearly 

 covering the zooecium above the one to which it belongs. The 

 orifices of fertile zooecia are about twice as large as those of ordinary 

 zocecia. 

 Localities. — Off Passage Island, Andamans, 17 fathoms; Marshall 



Slrait, Table Island. 



44. Schizoporella nivea, Busk. 



Voy. H.M.S. " Challenger," pt. xxx (vol. x), p. 163. 

 Locality. — Andamans (Wood-Mason). 



45. Sc'iizoporella aperta, Hincks. 



Ann. Mag. Nat. Hist., series 5, vol. ix, p. 126, 1882. 



These specimens correspond with those brought by Professor 

 Herdman from Ceylon and recorded by me (in Suppl. Report 

 XXVI to Herdman 's Ceylon Pearl Oyster Fisheries, pt. iv). They 

 have two spines on the upper margin of the orifice not mentioned 

 b)^ Busk. Ooecia are present here, not in the Ceylon collection. 

 The beaks of the large avicularia are not serrated as described by 

 Hincks {Ann. Mag. Nat. Hist., series 5, vol. ix). 

 Localities. — Coast of Cheduba, 28-30 fathoms (Armstrong) ; 8 miles 



E.S.E. Kalingapatam, 28-30 fathoms. 



46. Schizoporella spongitis, Pallas. 

 Locality. — Pedro Shoal, 25 fathoms. 



47. Schizoporella incrassata, Hincks. 



Ann. Mag. Nat. Hist., series 5, vol. ix, p. 124, 1882. 



The frontal, large avicularia have on this specimen forked 

 mandibles instead of pointed. Other characters correspond with 

 Hincks' description, but there are no ooecia to help in the identifica- 

 tion of the species. 

 Locality. — Off Ceylon coast, 32-34 fathoms (Indian Marine Survey). 



48. Schizoporella cecilii, Aud. 



Hincks, Brit. Marine Pol., vol. i, p. 269. 

 Locality. — Pedro Shoal, 25 fathoms.
