Part VII. — Further Observations on the Polyzoa, 



WITH the Description of a new Genus 



OF Entoprocta. 



By N. Annandai^Ej D.Sc, Siiperintendent , Indian Museum. 



A .considerable change has taken place in the Polyzoa of the 

 ponds this winter^ apparently owing to last summer's floods, which 

 broke down the embankment that separated the ponds from the 

 river, joining them together temporarih'. It will, therefore, be well 

 to publish the observations arising from a visit to Port Canning in 

 December, 1907, both as regards the species already recorded 

 and as regards a new genus that appears to have been introduced 

 since last winter. A comparison with European specimens, more- 

 over, has also made it necessar}^ to recognize the Bengal Victor ella 

 as a distinct species 



ECTOPROCTA.

The numerous colonies recenth^ obtained in the ponds are more 

 luxuriant than any I have seen before in India. Thanks to the 

 kindness of Mr. R. Kirkpatrick, of the British Museum, and Mr. 

 C. F. Rousselet, I have been able to compare them with some ex- 

 ceedingly beautiful preparations of the true Victorella pavida made 

 by the latter. In my former account of the form that occurs at 

 Port Canning, I stated that I had found no specimens in which the 

 proliferation was comparable in complexity with that of the colony 

 of which a part is figured b}^ Kraepelin in fig. 75, pi. iii of his 

 SUsswasser-Bryozoen. Examples taken in the ponds this winter, 

 however, are quite as complicated. The general appearance of the 

 colonies is that of a thick fur coating the grass stems, etc., on which 

 they grow. When free from green algae they are of a very pale 

 flesh-colour as a whole, some of the zooecia being tinged with j^ellow, 

 but the majority being practically colourless. The exact tint of 

 the stomach depends on its contents, but it has intrinsically a
