1897] A CARCINOLOGICAL CAMPAIGN 258 
us who think the spelling used by our scientific forefathers worth 
preserving. 
For number of remarkable novelties the palm is carried off by 
M. Jules Bonnier. He describes (1) six new genera and forty-five 
new species of sessile-eyed crustaceans, obtained by Prof. Koehler 
on board the “‘Caudan” in the Bay of Biscay. The depths ranged 
from 200 to 1700 metres. Out of 52 species taken 39 proved 
to be totally blind. The new Cumacean genus Procampylaspis, like 
Mr Walker’s Leuconopsis, displays an unexpected character, the 
‘finger’ or terminal joint of the second maxillipeds being cut into 
strong unequal teeth, giving the appendage what might almost be 
called an unnatural appearance. The rapid movement of modern 
science is exemplified in the circumstance that M. Bonnier’s new 
anthurid, Calathura affinis, is scarcely published before it has to be 
transferred, as it evidently must be, to Sars’ new genus Leptanthura. 
To the family Arcturidae M. Bonnier contributes a new species, 
Astacilla Giardi, which is remarkable not only for a quite abnormal 
appendage on the breast of the male, but also because the male is 
slenderly drawn out to a length thrice that of the female. The 
exiguity of the creature recalls the vermiform male of an anthurid 
discovered by Professor Haswell wriggling into serpula-tubes in 
Australia. Another of M. Bonnier’s striking results is the discovery 
of a crustacean parasite upon a Cumacean species. But this novelty 
also has been already transferred to a new genus by Dr H. J. 
Hansen, who, in a work noticed elsewhere, has described no less 
than seven new species of such parasites. 
Miss Mary J. Rathbun (8, 9) concerns herself only with the 
Brachyura, but, as in more than one of her recently described new 
species, the full-grown crab is less than the fifth of an inch in 
length, these species at least may be classed among the smaller 
crustaceans. On the other hand, M. Adrien Dollfus (6) speaks of 
a new woodlouse, Porcellio eximius, from the north of Africa, as 
“cette magnifique espéece.” It has the outer branch of the uropods 
in the male half as long as the body, as though it were a kind of 
peacock among woodlice, proud of its tail. Possibly these prolonged 
appendages enable their owner to execute strategic movements to 
the rear with caution and tact. 
Miss Harriet Richardson (10, 11) has this year described two 
new species of Sphaeroma, and given figures of one of them. The 
first is notable for its habitat, having been taken not from the sea 
but from a warm spring in New Mexico. The second is notable for 
its objectionable habits, having been found boring the piers on St 
John’s river at Palatka, Florida) The mischievous little creature 
has powerful jaws, and in eight years reduced timber of 16 inches 
diameter to less than half that measurement.
