 covered witii the same leafy flakes ; so tiiat, 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 trcc*trunk.

VII. — Suggested Terms in Crinoid Morpliology. 

 By F. A. Bather, 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 j\lagazine several notes on the Anatomical 

 Nomenclature of Echinoderms from the pen of the leader 

 whose loss we so deeply lament — P. H. Carpenter f. Tlie 

 object of that paper, however, was to give greater precision to 

 the }ionienclature of Echinoderm morphology rather than to 

 propose any great novelty. The object of the present paper 

 is different : it is 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 j: — "I think it may be taken as
