520 General Notes. [July, 
ared.1 From it we learn that only two American museums 
contributed, the Peabody Academy of Science at Salem, Massa- 
chusetts, and the Museum of Comparative Zoology, at Cam- 
bridge. The first of these papers treats of the Cirolanide, which 
closely resemble the true Cymothoas, but which differ in having 
the mouth parts adapted for eating flesh. Three genera and nine 
collaris, brevipes, nodosa and hirsuta are new. Each species is de- 
scribed as far as the specimens permitted, under three heads—male, 
virgin, and ovigerous females—the difference between the sexes 
and between the two forms of the same sex being very striking. 
In the second paper the Ægidæ are monographed. These Crus- 
tacea lead a parasitic life, generally attaching themselves to the 
roof of the mouth of fishes, and with their modified mouth parts, 
which form a sucking tube, living on the blood of their hosts. 
These forms are described under the following generic and spe- 
cific. names, those starred (*) being new: Alga tridens, hirsuta*, 
crenulata, webbi, stræmiü, rosacea, serripes, psora, deshayesiana, an- 
tillensis*, magnifica, monophthalma, nodosa*, opthalmica, tenuipes*, 
dentata*, incisa*, arctica, ventrosa and spong ciophila, Rocinela dan- 
monensts, insularis® dumerilii, opion , americana* , orientalis*, 
australis®, signata* and arte *, Alitropus typus and 'foveolatus*. 
Full descriptions are given of the male, virgin, ovigerous female 
and the young. The plates are engraved by Lovendal, the best 
rene scientific engraver, and are simply beautiful; the text is in 
n, which is far better for the man of average education than 
vould be the native language of the authors, and in short, the 
articles are models of scientific work. 
Mr. Edward J. Miers has at various times since 1874 published 
several valuable papers on the Crustacea, some of which have 
distributed in six genera. There is one feature of Mr. Miers’s 
work, which is to be especially commended; in these days © 
much species making, his tendency is just the reverse, and we
