FOSSIL CEPHALOPODA, DESCRIBED BY HYATT 



AND CRAGIN, IN THE MUSEUM OF THE 



UNIVERSITY OF TEXAS. 1 



ANNIE H. PRITCHETT. 



In the Second and Third Reports of the Geological Survey of 

 Texas, published in 1890 and 1892 respectively, Professor Al- 

 pheus Hyatt described a number of Nautiloids from material 

 collected in Texas under the direction of the then State Geolo- 

 gist, Mr. E. T. Dumble ; and in the Fourth Report, Professor F. 

 W. Cragin describes a number of forms, mainly Ammonites. 

 The material described in these three papers represents only a 

 portion, about an eighth, of a rather extensive collection of speci- 

 mens of these groups, but the portion that is most interesting 

 because of the number of type specimens. Only recently has 

 this material been unpacked and arranged, and because it is the 

 largest collection of the kind in Texas, and because for so many 

 years it has been inaccessible to students, it seemed desirable to 

 publish a short list of the more important specimens. The task 

 has been relatively simple, since in only a few cases had the 

 original labels been lost or misplaced ; and in most cases the de- 

 scribers had marked new species with the word "type." 



In the following list the name of each species is followed in 

 parentheses by the name of the particular describer, and the 

 volume and page of the published Report.
