1897J A CARCINOLOGICAL CAMPAIGN 253 



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 Procarrvpylaspis, like 

 Mr Walker's Leuconopsis, displays an unexpected character, the 

 ' linger ' 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 Lcptanthura. 

 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. Kathbun (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, Porccllio eximhis, from the north of Africa, as 

 "cette magnifique espece." 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 Eichardson (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.
