STATE GEOLOGIST. 127 



A little later a second brief contribution from this author was 

 published, but I have not seen it. 



Sir John Lubbock in 1863 describes species of fresh-water cope- 

 pods, but the publication seems no longer necessary. 



Heller, in Tyrol, Fric^ in Bohemia, and Uljanin, in Asia, have 

 studied the copepod fauna. 



A Russian paper by Poggenpol and Uljanin is quoted as "A 

 Catalogue of the Copepoda, Cladocera and Ostracoda of the vicinity 

 of Moscow," by Rehberg, and as from the Protokolle der kais.-na- 

 turiv. anthropol. und ethnogr. Ges. in Moskau, but by Cragin who 

 publishes a translation apparently of the same paper, in part, as 

 from the " Bulletin of the Friends of Natural History." 



Hoek, in the TijdscJirift der Nederlandsche Dierkundige Vereeni- 

 ging (Magazine of the Zoological Society of the Netherlands) 1875, 

 and later in Grerman in the Niederlaendisches Archiv fiier Zoologie, 

 gave excellent figures and descriptions of some species which Ciaus 

 had too hastily treated. 



In 1878 A. Gruber gave descriptions of "Two fresh-water Cala- 

 nidae,'' 



In the same year the first volume of Brady's fine '"''British Cope- 

 oda " appeared. A purely technical work and briefly written, it is 

 yet very comprehensive and in the main reliable. This is a worthy 

 successor of the Ray Society^s earliest publication on entomostraca 

 — Baird's great work. 



In the sixth vol. of the Abhandlungen d. naturwissenschaftlichen 

 Vereine zu Bretnen, Herman Rehberg gives a systematic review of 

 synonomy, and in the revision unites several species in a manner 

 that the present vrriter had independently been driven to do. It is 

 probably impossible either to substantiate or positively deny some 

 of this writer's identifications of the species of the older authors. 



This paper also contains an observation of a hermaphroditic Cy- 

 clops, which it is interesting to compare with similar anomalies, 

 described by Kurz in Cladocera. 



In the vii Band of the same periodical, Rehberg adds to and 

 modifies some of the views expressed above. In the same number 

 is a description of a new species of Temora by Poppe. (The same 

 species occurs in the semi-saline waters of the Gulf of Mexico, and 

 had well-nigh gone into print under a new name when this was 

 seen.) 



In the above review we hafe noticed only the more important 

 foreign works on the Copepoda and those including fresh-water 

 forms. Dana's magnificent Crustacea of the Wilkes'' Exploring
