In Wy ville Thomson's ' Depths of the Sea,' 1 873, p. 463, 

 it is stated : " Gerithium granosum, S. V. Wood, is also 

 common to Norway and Shetland; " and I myself have a 

 small dead specimen which was given me by my late friend 

 Mr. E. Waller as from " Shetland ; " but Jeffreys does not 

 give a station in his report which is in the Shetland Sea. 

 The following, however, establish its claims to be included in 

 our fauna :— ' Porcupine,' 1869, St. 23 a, lat. 56° 13' N., 

 long. 14° 18' W., that is, south of Rockall in 420 fathoms; 

 Stations 89 and 90, which were on the ' Holtenia ' ground, 

 N.W. of the Butt of Lewis, lat. 59° 38' to 41', long. 7° 46' 

 to 34' W., in 445 and 458 fathoms. 



It was also taken to the north of our area by ' Lightning,' 

 St. 2, and ' Porcupine,' 1869, St. 65. I have myself dredged 

 it in several places on the west of Norway, and Sars has 

 recorded it from Finmark. As a fossil it occurs in the Red 

 and Coralline Crags, and also in the Antwerp Crag. 



BIBLIOGKAPHICAL NOTICES. 

 Insects, their Structure and Life. A Primer of Entomology. By 



Geokge H. Cakpenter, B.Sc. Lond. Pp. xi, 404. London, 



J. M. Dent & Co. 

 In this useful little book Mr. Carpenter has given a sketch of the 

 structure of insects in general (the cockroach being taken as a typical 

 example), and an abstract of the classification, structure, habits, and 

 pedigree of insects, not forgetting to add a Bibliography and Index. 

 Although the book does not profess much originality, it is well 

 arranged, and contains a large amount of information which it 

 would require much time and trouble to collect elsewhere, even with 

 the aid of the bibliography which Mr. Carpenter has appended to 

 his work. The non-technical portions (those dealing with habits, 

 evolution, pedigree, &c.) are written in a very clear and pleasing 

 style, and may interest many readers who might not care for the 

 more technical parts of a work on entomology ; for the subject is so 

 vast and varied that it presents ample materials for study, equally 

 to the systematist, the comparative anatomist, the field naturalist, 

 the geologist, the philosopher, and the amateur who wishes for as 

 much general superficial knowledge of everything as he can obtain. 



It is not to be supposed that a book of such a comprehensive 

 character can be free from error ; but although we may not 

 always agree with the author's conclusions, we have not noticed 

 anything which we should be disposed to regard as seriously 

 detracting from its value. The amount of space devoted to difFerent 

 parts of the subject, the reliability and real importance of various 

 observations and experiments, the mutual affinities of diflerent 

 families of insects, the probable number of existing species of 

 insects, and the problems of Evolution and Geographical Distribu- 

 tion are all subjects on which no general consensus of opinion can 

 at present be expected.
