Calcareous bodies are few in number, as in 7: so/ium, but only about 
one-tenth as large; they are of about the same dimensions as those 
of 7: saginata, but much less numerous. 
Other characters enumerated by Guyer might be mentioned, in 
respect to which 7: confusa occupies an intermediate position between 
T. saginata and T. solium. How widely the new species occurs is, of 
course, unknown. It may be that the existence of this intermediate 
species has merely been overlooked heretofore; another possibility 
suggests itself — can it be that these apparently rare specimens are 
hybrids between 7: solium and T. saginata, a thing, to be sure, unheard 
of heretofore, but not for that reason impossible. WEL: 
Zoological Results of Dr. Willey’s Collecting Trip.! — Natural- 
ists have been looking with eager anticipation for the publication of 
the results of the three years’ expedition of Dr. A. Willey to New 
Britain, New Guinea, and the Loyalty Islands. These results have 
now begun to appear in book form. Part I has just come to hand. 
This volume comprises papers by Dr. Willey on the Anatomy and 
Development of Peripatus Nove-britannie ; P. Mayer, Metaprotella 
Sandallensis, x.s. [Caprellida]; Boulanger, on a Little-known Sea 
Snake from the South Pacific; Pocock, Report on the Centipedes 
and Millipedes ; Sharp, Account of the Phasmidz, with notes on the 
eggs; Pocock, Scorpions, Pedipalpi, and Spiders. 
The account of the new Peripatus is perhaps of most general inter- 
est. It represents a new-subgenus, Paraperipatus. The ova are small 
and without yolk, and many embryos, in all stages of development, 
may occur in the uteri of one female. The embryos lying in the 
uteri receive nourishment from the mother and are born in a more 
complete condition than in any other species of the genus. This 
paper is accompanied by four plates. 
The Common Toad. — It is a matter of congratulation for teachers 
of nature studies in our schools when a well-trained scientific worker 
will turn aside to put in an attractive form the story of a common 
object. This has been done by Prof. S. H. Gage, who in a pamphlet 
of some twenty pages has given an account of the life history and 
habits of the common toad.2 The treatment of the subject, while
