brates of Indiana, his first paper upon the birds dating from 1882. 
In 1890 he published an annotated catalogue (135 pages) of the birds 
of the state, and now we have a more pretentious paper from him,? 
enumerating 321 species actually known from the state, and in a 
supplementary list 81 additional species, which, while occurring in 
adjacent states, have never been reported from Indiana. The present 
volume is more than a catalogue; it is a manual of the ornithology 
of the state, with analytical keys, descriptions of the species, and 
bits of bird biography, some copied, but many original and showing a 
familiarity with the birds in the field. A greater value to the agricul- 
turist is found in the accounts of the economic importance of many 
species, especial stress being laid upon the food and upon the agency 
which many birds perform in the distribution of the seeds of useless 
and noxious plants. The American Naturalist has often had occasion 
to speak in high terms of the zoological work done in Indiana, and 
this work by Mr. Butler is but another instance in the same line. 
Fishes of the Canary Islands. — In the Proceedings of the Academy 
of Natural Sciences of Philadelphia is a list of fishes collected by 
O. F. Cook, at the Canary Islands. Fifty-four species are enumer- 
ated, four of them new. ‘The fauna of these islands is essentially 
that of the Mediterranean, showing little in common with the West 
Indies. There are, however, some differences from the Mediterra- 
nean fauna, appearing in the fact that some of the common types of 
the latter are replaced by closely allied but distinct species. There 
is no evidence of difference between the Canary fish fauna and that 
of the Madeiras. 
Development of Chilopods. — All facts concerning the develop- 
ment of the Chilopoda are of interest, and this short paper by Dr. 
Heymons? contains much of importance. A complete paper is prom- 
ised later, The egg contains a central unsegmented yolk with seg- 
mentation nuclei. Some of the segmentation cells migrate to the 
surface and from the blastoderm. The yolk-cells arise in part from 
the nuclei which remain in the yolk, in part from elements which 
arise from the blastoderm. These immigrant yolk-cells cannot be 
distinguished from the entoderm cells, which arise in the same manner 
from all parts of the ectoderm. A gastrular groove does not exist.
