1895- SOME NEW BOOKS. 351 



habits and character, but, unfortunately, says less about their 

 physical features. The conclusions which he has arrived at 

 independently in regard to the affinities of the tribe are better than 

 some which he has accepted, apparently somewhat reluctantly, in 

 deference to opinions of men whom he regarded as high authorities. 



A few defects and deficiencies in special parts of the book 

 cannot, however, seriously detract from its value and importance ; 

 and the author must be congratulated on an important addition to the 

 literature of East Africa. Captain Swayne's work is more business- 

 like and instructive than James's racy narrative ; it is more reliable 

 and juster in its judgments than Burton's " First Footprints in 

 East Africa " ; and it is more generally intelligible and interesting 

 than the detailed, scientific monographs of Paulitschke. It may be 

 confidently recommended as the best existing account of our new 

 protectorate of Somaliland, of its game, and of its people.

Dr. Bigelow here furnishes valuable analytical keys to the genera 

 and species of the Squillidae in general. He supplies figures and 

 detailed descriptions of the fourteen new species which he had already 

 established in 1893. Odontodadylus, which in that year he separated 

 from Gonodactyhis as a subgenus, is here raised to the rank of a genus. 

 He accepts in all nine genera of Squillidee, whereas H. J. Hansen, in 

 his Stomatopoda of the Plankton Expedition, 1895, reduces the 

 number to seven. But Dr. Bigelow retains the Leptosqiiilla of Miers 

 and the Pterygosqnilla of Hilgendorf with a hesitation which almost 

 amounts to dismissing them. Hansen includes them both under 

 Sqnilla. The Pvotosqnilla of Brooks, admitted as valid by Bigelow, is 

 re-united to Gonodactyhis by Hansen, who, on his own account, 

 assigns Pseudosqinlla stylifeva (Milne Edwards) to a new genus, 

 Hemisquilla. 



Under the name of " the Odonterichthus larva," Dr. Bigelow 

 exhibits two forms as probably the young of Odontodactylus. The larvae 

 of Stomatopoda, he says, are sometimes to be found in immense 

 schools. When working at Bimini Islands, Bahamas, in the summer 

 of 1892, he found a few of these larvae of various kinds and stages 

 almost every time that the towing-net was used ; but after dark on 

 three successive evenings in July the towing-nets were crowded with
