Ii6 The Irish Naturalist. October, 1922, 



Mr. Stelfox and Cybele II. 



In the August number of the Irish Naturalist, Mr. Stelfox states 

 (E* 99) that Trijolium suhterraneum and T. glomer.atum appear to have 

 been generally regarded as aliens. In a footnote on the same page, 

 be corrects this statement as regards IVfr. A. G. More who in " Recent 

 Additions," 1872, recorded both plants as " undoubted natives " ; in the 

 same note Mr. Stelfox then proceeds to accuse the " editor " — there were 

 two of them — of Cybele II. of being the " first and last " so to regard 

 them. May I ask Mr. Stelfox where these plants have been treated as 

 aliens in Cj^bele II. ? 



On pp. 83 and 86 of that work, these two clovers Mall be found with 

 a t prefixed, and on p. Ixxii. in the Introduction the f is explained as 

 indicating " a slight suspicion of having been introduced by the agency 

 of man " ; an * being used for those " certainly introduced." 



In 1898 when Cybele II. was published, the late Mr. Coigan and I 

 were quite agreed that both these plants should have the sign f, and in 

 1922, as regards T. suhterraneum, I am still of the same opinion.

REVIEW. 



A MUSEUM HANDBOOK. 



The Horniman Maseum : A Handbook to the Collections illustrating 

 a Survey of the Animal Kingdom. By H. N. Milligan. Second 

 Edition. Pp. 66. London County Council. 1922. Price 6d. 



Three pages on some elements of morphology are followed by an 

 account of the Animal Kingdom in 61 pages, under fourteen phyla, from 

 Protozoa to Chordata. The Echinodermata are placed between Mollusca 

 and Arthropoda, which is scarcely a " conservative " position. Surely 

 such arguments as there are would lead one to place them next the 

 Chordata. The statements are as accurate as can be expected in an 

 account that must combine brevity with intelligibility and has small 

 room for the qualifications demanded by meticulous precision. For 

 example, the theory of the origin of Echinoderms from bilateral [non- 

 echinoderma.l] ancestors through fixed forms postulates that " the mouth 

 was directed [at first downwards and then moved] upwards." Mr. 

 Milligan's omission of the words in square brackets conveys a wrong 

 impression. Since the Echinoderms are allotted a page more than either 

 Molluscs or Arthropods, they might, perhaps, receive more careful 

 statement. Two pages at the end of the book suggest how the beginner 

 may proceed with the study of zoology.
