The zoocecidia of plants in Germany and their occupants, edited by 

 E. H. RiJBSAAMEN {Zoologica, 2-'/ (1911), No. 61, pt. 1, pp. 293, pis. 0, figs. 3).— 

 The first paper of this work (pp. 1-104), by F. Thomas, consists of an index of 

 the literature up to the close of 1906 on the animal galls of Germany and their 

 occupants. The second paper (pp. 105-165) consists of a general account by E. 

 Ktister of animal galls and their occupants. The third paper (pp. 107-293), 

 by A. Nalepa, is devoted to the eriophyid gall mites, their structure, develop- 

 ment, ecology, and classification. 



The animal kingdom. — Ixodidse, L. G. Neumann (Das Tierreich.^ — Ixodidfr. 

 Berlin, 1911, No. 26, pp. XVI+169, figs. 76). — In this systematic treatment of 

 the ticks, the author divides the family Ixodidse into 2 subfamilies, namely, the 

 Ixodinte, including the sections Ixodini and Argatini, and the Spelajorhynchinse, 

 represented by the single species Spelceorhynchus prceciirsor described by 

 Neumann in 1902 from a specimen collected from a bat (CaroUia hrevicauda) 

 in Pernambuco. 



The section Ixodini is divided into 3 tribes, namely, Ixodaria, including the 

 genus Ixodes with the 3 subgenera Ixodes, Ceratixodes, and Eschatocephalus; 

 Rhipicephalaria, including the genera Rhipicephalus, Margaropus, and Hya- 

 lomma; and Amblyommataria, including the genera Amblyomma, Aponomma, 

 Dermacentor, and Hsemaphysalis. The section Argatini is represented by the 

 genera Argas and Ornithodoros. 



A synonymical bibliography and description, together with host and dis- 

 tribution lists, is given for each species. Tables for the separation of species, 

 a systematically arranged host list, and an index are also included. 



The preparation of this work was completed on February 29, 190S. 



Ticks: A monograph of the Ixodoidea, II. — Ixodidae, G. H. F. Nuttall and 

 C. Warburton {Camhridge, 1911, pp. XIX+105-348, pis. 4, figs. 193).— This 

 second part of the authors' monograph (E. S. R., 21, p. 562) is divided into two 

 sections, the first dealing with the classification of ticks, and the second with 

 the genus Ixodes. 



Under the genus Ixodes the authors give the synonymy and literature, and 

 keys for the determination of the species based upon males, females, nymphs, 

 and larvffi so far as the material at hand has permitted. Technical descrip- 

 tions of 51 species which the authors consider valid and of varieties and sub- 

 species follow. The synonymy, iconography, bibliography, descriptions of the 

 stages, and geographical distribution are given for each species. These de- 

 tailed accounts of the species are followed by a list showing the geographical 

 distribution of the genus, a list of condemned and doubtful species of Ixodes, 

 including their synonymy and literature, notes on doubtful species of Ixodes, 

 and notes on the biology of Ixodes by G. H. F. Nuttall (pp. 294-317). Two ap- 

 pendixes include reprints of papers (1) on The Process of Copulation in 

 Ornithodorus mouhata (pp. 318-323), by G. H. F. Nuttall and G. Merriman,« 

 and (2) On the Adaptation of Ticks to the Habits of Their Hosts (pp. 324-345), 

 by G. H. F. Nuttall.^ An index to the valid species of Ixodes, together with a 

 list of the collections in which the types are to be found, is included. 



Ticks: A monograph of the Ixodoidea. — Bibliography of the Ixodoidea, 

 G. H. F. Nuttall. L. E. Robinson, and W. F. Cooper {Camhridge, 1911, pp. 

 VI+68). — This bibliography, which contains 2,004 titles, deals with ticks and 

 their relation to disease. It is arranged by authors, and includes the date of 

 publication.
