BIBLIOGRAPHICAL NOTICE. 



Smithsonian Institiitio7i: United States National Museum. Special 

 Bulletin. American Hijdi'oids. — Part 11. 7'/^e Sertularidte. With 

 41 Plates. By Charles CLEVELvyo Nutting, Professor of Zoology, 

 University of Iowa. Washing-ton : Government Printing Office, 

 1904. sin. fol. Pp. 151. Index, pp. 310-3.5. 



The first volume of this work included the Plumularidae, which had 

 been supposed to be a much larger family than the Sertularidae, of 

 which latter family only about 20 American species had been 

 mentioned in any single work. But by bringing together the 

 scattered literature and by the description of upwards of 3 i new 

 forms Prof. Nutting has been able to describe and in most cases to 

 figure as mauy as 130 species in the present work. We are pleased 

 to see that he has been largely assisted by contributions of specimens 

 and literature by the authorities of the British Museum (for por- 

 tions of a number of Allman's ' Challenger ' types) and numerous 

 co-workers in. Europe and America. 



The work commences with an essay (with good text-illustrations) 

 on the Morphology of the Sertularida), which is considered to be 

 zoologically a lower family than the Plumularidae, and which has 

 hitherto been somewhat neglected. The various classifications are 

 then discussed, and tables of genera and of the geographical distri- 

 bution of the species are given. Then follows the systematic 

 portion of the work, with full descriptions of the genera and 

 species, the latter being tabulated under each genus and afterwards 

 dealt with under the heads of Synonymy, Trophosome, Gonosome, 

 Distribution, and Pemarks. The collection in which the type is 

 contained is also frequently indicated. The work concludes with 

 au annotated Bibliography, a list of works to which reference is 

 made in the synonymy in the systematic part of this work, but 

 which have not been consulted by the author, and the explanation 

 of plates, preceding the plates themselves. It forms a handsome 

 volume, and appears to be an excellent piece of work.
