THORNELY POLYZOA 159 



It is notable that only seven species in the Kattiawar list are recorded in 

 Waters' list of Red Sea species (" Repts. Soudanese Red Sea," Journ. Linn. Soc. 

 Vol. XXXI., Nos. 205 and 207, 1909-10), viz. : Scrupocellaria cervicornis, Nellia 

 oculata, Bugula neritina, Synnotum aviculare, Tkalamoporella rozieri, Microporella 

 ciliata, and Cylindroecium giganteum, and that all these are cosmopolitan species ; 

 the six first extend from the Atlantic Ocean (or Mediterranean) eastward to 

 Australia, while the seventh, Cylindroecium giganteum, is recorded from British 

 Columbia, Britain, and the Mediterranean and Red Seas. 



The chief conclusion to be drawn from this comparison of collections appears 

 to be that the polyzoan fauna of Indian Seas is still most imperfectly known and 

 requires much more study before any useful deductions upon geographical dis- 

 tribution can be drawn. J. HORNELL.]
