Alacran shoals, during the Antillean cruise of the yacht Utowana. Aan itin- 
erary gives information as to the time devoted to each station, and a second 
part will'contain a detailed account of the ecological observations, and also 
the plates made from the many fine photographs secured. The list of species 
is surprisingly long when one considers the shortness of the time and the 
often unfavorable conditions for collecting. Thirty-four new species are 
described, distributed from the fungi to the Compositae. —J. M. C. 
Mr. E. W. HERVEY, of New Bedford, Mass., has published independently 
his observations on ‘The colors of flowers.’’5 In it he records a large 
amount of work which might have been better directed had he made himself 
familiar with the rather extensive literature on the subject. Ina section on 
the sequence of color he assails with a vigor and directness worthy of a better 
object the shallow generalizations of Grant Allen on this subject. His pres- 
entation has no logical sequence and no definite marshaling of the many 
discrete facts which he has gathered respecting the relation of insects to 
color, nor any adequate correlation of these facts with the host of previous 
observations.— C. R. B.
