account we do not gather that any other aquarium than that of 

 Brighton condescends to the Music Hall entertainment combination. 



Memorias de la Sociedad Antonio Alzate, vol. ix., nos. 9 and 10, 

 contains papers by Dr. A. Duges on the foot of monkeys and the 

 skeletons of the bird and the tortoise, and one by Dr. R. E. Cicero 

 on the medical habits and knowledge of animals. 



Readers of Dr. Axel Ohlin's paper. " A Zoologist in Tierra 

 del Fuego " (Nat. Sci., Sept., 1896) should be interested in an 

 account of recent explorations in the Patagonian Andes, 41° S. lat., 

 by Dr. Hans Steffen, in the Scottish Geographical Magazine, Feb., 1897. 



Additional information concerning the huge octopus that we 

 alluded to in our February number, p. 130, is given by Mr. A. E. 

 Verrill in the February number of the American Journal of Science. It 

 is a true octopus, with a body 21 feet long, and almost 7 feet wide. 

 A stump of an arm still attached reaches the length of 36 feet, and 

 was 10 inches in diameter where it was broken off distally. The parts 

 cast ashore probably weigh at least six Ions, and the total mass, 

 when living, was probably twice that weight. The drawings of it will 

 be published in the American Naturalist. Mr. Verrill names it Octopus 

 giganteus, but considers that it may be allied to Civroteuthis. To this 

 number Mr. Verrill also contributes an interesting note on nocturnal 

 and diurnal changes in the colours of certain fishes and of the squid 

 (Loligo), with notes on their sleeping habits. The nocturnal colours 

 are obviously protective, and the positions assumed by the fish while 

 sleeping are often quaint and unexpected. In another note Mr. Verrill 

 considers that the nocturnal coloration of various animals has been 

 selected on account of its protective value. This number also begins 

 the long-looked-for outline of a natural classification of the Trilobita, 

 by Dr. C. E. Beecher. 



In the Geological Magazine for February, Dr. J. W. Gregory dis- 

 cusses the fossils on which Dr. H. Hicks recently based his claim that 

 the Morte Slates of North Devon were of Silurian age. He concludes, 

 from examination of the specimens, that they belong not to the 

 Silurian genera, to which the President of the Geological Society 

 assigned them, but to characteristic Devonian genera. Whoever may 

 ultimately prove right, it is clear that such obscure material as has 

 hitherto been the sole reward of Dr. Hicks' laudable perseverance is 

 not enough to warrant a re-arrangement of the stratigraphy.
