plant*. The area immediately surrounding the doors is 
covered with the same leafy flakes ; so that, when closed, the 
doors become almost invisible. The nest itself consists, not 
of an elongate silk-lined tube, as is usual in this group, but 
simply of a shallow excavation on the surface of the tree-trunk.

VII.—Suggested Terms in Crinoid Morphology. 
By F. A. Batuer, M.A. 
It is to be feared that the title of this paper will bring a smile 
to the lips of those who think, not without some show of 
reason, that students of Crinoid morphology spend more time 
in quarrelling as to what terms they are to use than in finding 
out fresh facts that should warrant any departure from the 
language of the text-books. It is not long since there 
appeared in this Magazine several notes on the Anatomical 
Nomenclature of Echinoderms from the pen of the leader 
whose loss we so deeply lament—P. H. Carpenter ft. The 
object of that paper, however, was to give greater precision to 
the nomenclature of Echinoderm morphology rather than to 
propose any great novelty. ‘The object of the present paper 
is different: itis to propose certain changes in the terminology 
of the various parts of a Crinoid, partly because it is hoped 
that these changes will facilitate the drawing up of descrip- 
tions and give greater clearness to our ideas, partly because 
it is believed that they are necessitated by recent advances in 
Crinoid morphology. 
Every scientific paper should be its own apology ; at the 
same time some reply may be offered to two different classes 
of objectors. 
Those who have an innate objection to all change may be 
answered by the following quotations from a recent article by 
Prof. T. Jeffery Parker $:—“I think it may be taken as 
* I am indebted to my colleagues of the Botanical Department of the 
Natural-History Museum for this information respecting the nature of 
the substance of which these doors are composed.
