Points of Special Interest. 



(1) The discovery of Tubulipora (Proboscina) Lanwurouxii, Audouin, which 

 has never been understood, so that the generic name Proboscina has been 

 incorrectly used by some authors for forms allied to Stomatopora : p. 31. 



(2) The way in which certain species of Sclrizoporella grow in layers, with 

 the younger layer taking definite positions, frequently passing over the 

 opercula. Together with this, the closures of the Cheilostomata are con- 

 sidered : pp. 15 & 16. 



(3) The spines surrounding the zooecia of Cribrilina radiata, Aud., and 

 the formation of the zooecia are considered : p. 11. 



(4) A very interesting Lichenopora with confluent zoaria is more fully 

 described. Some subcolonies are multiserial, others uniserial, and it is 

 difficult to decide whether they should be considered as one or two species : 

 p. 33. 



(5) Several points relating to the classification of Crista are dealt with : 

 p. 24. 



The collections inade by Mr. Cyril Crossland consist of 45 species or 

 varieties, of which 25 were already known from the Atlantic, 16 are British, 

 24 Mediterranean, and probably 17 are Australasian. Besides these, a list 

 of 41 species already described from the Cape Verde Islands is given.
