 In the fauna of this region the author enumerates, giving brief descriptions copied 

 or adapted from Hall and Simpson's Paleontology of New York, VI, or Simpson's 

 Handbook of Genera, some forty species of bryozoa. Diagnoses are also given of the 

 genera used. One new species appears, Monotrypa amplectens.

 In the fauna is noted the occurrence of seven species of bryozoa. In a later work,

 and Missouri. (Kansas University Quarterly, ser. A, IX, No. 1, 

 January, 1900, 12 pp., pis. i-iv.) 



This paper came to hand too late to be incorporated into our work at any point 

 but this. It contains good descriptions and figures of the following species, all new: 

 Stenopora spinulosa, spissa, Cystodictya inequimarginata, divisa, Streblotrypa ulrichi, 

 striatoijora, Fenestella hexagonalis, dentata, kansasensis, ovatipora, missouriensis, 

 Polypora aspera, flexuosa, elliptica, triangularis, Thamniscus tenuiramus, Pinnato- 

 pora pyriformipora, ptiloporoidea, multipora, Septopora interporata, Acanthocladia 

 pinnata, Rhombocladia delicata. 



Rhombocladia is a new genus which the author refers provisionally to the Acan- 

 thocladiida'. Streblotrypa ulrichi is a synonym for Streblotrypa prisca (Gabb and 

 Horn ) .
