Mr. E. Doubleday on some neiv species of Butterflies. 415 



for its reception. De Blainville adopted tlie gen.us, modifying the 

 character as follovrs : — 



" Animals pulypiform, sessile^ not retractile, provided with 

 eight pinnated tentacula, arranged quiucuncially on one side only 

 of the posterior half of a free, regular, quadrangular and much 

 elongated rachis.^^ (Actinologie, p.SlG.) 



This genus appears well-founded, and the species will accord- 

 ingly stand as Pavonaria quadrangularis (sp.), Pallas. 



In Loch Fine Mr. MacAndrevr dredged a tine specimen of the 

 remarkable and rare zoophyte knov>'n to British naturalists as 

 " Zoanthus Couchii." It has not hitherto, as far as I am aware, 

 been noticed on the Scottish coasts. 



All the above-mentioned annuals were exhibited to the Natural 

 History Section at York. It is very desirable, since most of the 

 naturalists engaged in the investigation of the indigenous fauna 

 and flora are members of the British Association, that from year 

 to year new and rare forms of British animals and plants should 

 be brought forward at the annual meetings of that body, and so be 

 rendered famihar to many who might not otherwise have an op- 

 portunity of examining them. The chief interest of the Section 

 will always depend on the meeting of the practical investigators 

 of the zoology and botany of the British Islands, and of the sta- 

 tistics of natural history, with those naturalists wliose attention is 

 directed to the philosophy of the science and to the investigation 

 of structural and physiological questions. This has been the cha- 

 racter of the Section during the last two meetings, and promises 

 happily to be permanent and to be tlie means of elevating the 

 reputation of this department of British science among our con- 

 tinental brethren, who a few years ago were not much inclined 

 to admit the probability of our going ahead in the higher branches 

 of biological science. The more suggestive the character of the 

 meetings of Section D. is rendered, and the less there is of frivo- 

 lous disputes as to who first named this species or who named 

 that, without reference to structure, habits, law and locality, the 

 better.
