' North American Tertiary Species, described by Messrs. Gabb & Horn.' 



I have already given selections from this monograph when dealing 

 with Cretaceous Polyzoa, and now that I have to give the list of Tertiary 

 fossils, I am confronted by a difficulty as to the horizon of the species. 

 The authors speak of ' Miocene ' and ' Pliocene,' but in two foot-notes, one 

 especially below Cellepora formosa, I find the following : ' In regard to 

 the use of the terms " Pliocene " and " Miocene " in this country, it will 

 probably be found on more careful examination that there is no real 

 division existing between the two so-called formations ;' and at the end of 

 the monograph is the following : ' Since the writing of this monograph, 

 Mr. W. M. Gabb has been called to the post of Palaeontologist to the State 

 of California. In regard to the Santa Barbara and the San Pechs deposit 

 he writes, they are amongst the most recent deposits, almost all the 

 species being still extant. Instead of Post-Miocene, they should be called 

 Post-Pliocene.' 



In their identifications of species, the authors give many synonyms 

 from D'Orb. and Lonsdale, but when Prof. Smitt wrote his ' Floridan 

 Bryozoa,' he could only identify about three species as belonging to 

 recent Polyzoa ; these are given in the text. I wish, however, to direct 

 the attention of students towards the Fossil Polyzoa of North America, 

 Cretaceous and Tertiary, for from what I have been able to judge of 

 species sent to me I feel confident that a rich harvest of forms has yet 

 to be described from many localities ; and it is to be hoped that future 

 students will direct more special attention than has yet been given to the 

 purely structural features so ably formulated by both Hincks and 

 Waters, full details of which will be found in the former part of this 

 report. In this monograph also I have adhered to the text and arrange- 

 ment of the authors. As a piece of palreontological work I cannot speak 

 very highly of this monograph. The creation of new names — both of 

 genera and species — is much to be regretted. However, I have done as 

 full justice to the work as was possible under these circumstances.
