that the vertebrae may be composed of two successive pairs of 
ambulacral elements, and reasons are given for suspecting that this 
may be the case in all the more advanced Ophiurids. ‘The holotype 
of the species, which is the first echinoderm described from these 
Cornish slates, is in the British Museum. 
In recent numbers of the Bulletin du Musée Océanographigue de 
Monaco, E. Chevreux describes two new deep-sea amphipods, Cypho- 
caris alicei and C. richardi, from the waters between the Canaries 
and the Azores. G. O. Sars contributes the first part of a prelim- 
inary list of the Calanoids collected during the Prince of Monaco's 
deep-sea explorations. A list of the Symphyla and Diplopoda of the 
principality of Monaco is given by H. W. Brölemann. 
The migratory movements of certain species of Pierids in the 
Amazon valley are described by Dr. Geeldi in vol. 4 of Boletim do 
Museu Geldi. The same journal contains a list of the Brasilian 
birds described by Spix, Wied, Burmeister, and Pelzeln, and a cata- 
logue of the mammals in the collection of the Para Museum. A 
number of interesting notes on the mammals are added and well 
executed plates illustrate several of the species.
