wish he would “get rid of that terrible word ‘ urinogenital.’” On 
page ıgo the suprasternal bones are spoken of as cartilaginous in 
origin, and are also regarded as representing the episternum of the 
lower vertebrates, but the episternum is membranous in origin. On 
page 202 there is a confusion in relation to the maxillary bones and 
“their cartilaginous representatives" in the lower vertebrates. The 
printing of the new edition is an improvement on the first, especially 
that of the cuts. We commend the work in the highest terms as a 
clear; accurate; and modern account of the development of man.

The Arthropods and Celenterates of the Maldive and Lacca- 
dive Archipelagoes.! — In this part of this work are five articles deal- 
ing with certain groups of Arthropods and Ceelenterates and a notice 
of two parasitic worms. Professor S. J. Hickson treats of the Gor- 
gonacea and certain other Alcyonarians, Thirteen species of.Gor- 
goniids are enumerated, of which six are regarded as new, all coming 
from water of thirty fathoms or less in depth. A single species of 
Pennatula was found and a new species of. Eunepthya is described. 
Mr. Borrodaile deals with the twenty-three species of hydroids col- 
lected, eight of them being new. Lictorella shows some interesting 
features, there being, besides the normal hydrotheca, others. nearly 
four times as large, each with a hydranth at the bottom. These are 
regarded by Borrodaile as gonothecz, although no gonophores were 
found, and on this account he would not agree with some authorities 
in uniting Lictorella with Lafcea, since in the former there would not 
be any Coppinia condition. Synthecium also presents some prob- 
lems for. solution. An interesting habitat is recorded for an uniden- - 
tified species of Campanularia. It occurred attached to the body of 
a sea snake. Borrodaile recalls in this connection a similar associa- 
tion of a species of Stylactis with a fish but has overlooked Fewkes’ 
Hydrichthys mirus which occurred on a teleost on the south coast of 
New England. À P 
The hermit crabs are discussed by Major Alcock, who enumerates 
twenty-six species, of which four are new. The shrimps of. the fam- 
ily Alpheidæ were especially numerous, and H. Coutière enumerates 
seventy-six species belonging to the group, a large proportion of 
these being regarded. as new. Twenty species of Hemiptera are
