Cagliari, which are probably of Miocene age. Prof. Capellini first 

 gives us a plate illustrating the specimen in the condition in which 

 it was obtained from the quarry, and then a larger plate showing 

 the skull completely extracted from its matrix. All the characteristic 

 features of the genus Toniistoma are displayed in these plates, so 

 that there is no donbt as to the correctness of the generic determina- 

 tion. The general characters are also very similar to those of the 

 Austrian T. eggenhurgense (which the author considers is rightly 

 included in Tomistoma, although originally described as Gavialo- 

 suchus) ; but the snout is relatively shorter and thicker, and the 

 supratemporal foss^ are more nearly circular. 



The gradually accumulating evidence of the abundance of Tomistoma 

 during the Tertiary period in Eui'ope shows conclusively that the 

 solitarj' existing species of the genus is one of the many instances of 

 the survival in the Oriental region of ancient European types. 



We may mention in passing that the author adopts the amended 

 name Garialis in place of the ordinary and incorrect Gavialis.

II. — Dr. Otto Jakel on Perforating Fungi in Fossil Elasmo- 



BRANCH Teeth. 

 "Gangk von Fadenpilzen (Mycelites ossifragus, Roux) in Dentin- 



BiLDUNGEN." By Otto Jaekel. [Sitzungsb. Ges. naturf. 



Freunde, 1890, pp. 92-9i.] 



DUEING the microscopical examination of sections of the fossil 

 rostral teeth of Pristiophoi-ns, Dr. Jaekel observed the minute 

 branching tubes of a boring organism. The latter he regards as 

 a fungus already described by W. Roux as infesting bones and teeth. 

 Similar borings are recorded in " Splienodus ornati," Corax lieterodon, 

 Acanthias orpiensis, Kotidanus primigenius, and a new extinct species 

 of Tri/gon. We would add that similar borings have already been 

 noticed in fish-scales from the English Chalk. 



III. — Dr. W. Dames on a Nothosatjrian Reptile from the 



MUSCHELKALK. 



" Anarosauriis piimilio, nov. gen., nov. sp." By Prof. W. Dames. 

 [Zeitschr. deutsch. geoL Ges. 1890, pp. 74-85, pi. i.] 



THE author describes the remains of the head, neck, and abdominal 

 region of a small Nothosaurian, from the Lower or Middle 

 Muschelkalk of Eemkersleben, west of Magdeburg. The specimen 

 is preserved in the Eoyal University Museum, Gottingen, and it is 

 well shown with its counterpart, of the natural size, in the jjlate 

 accompanying the memoir. At first sight the reptile appears to be 

 a miniature JV^othosaiirns, but it is considered to be generically 

 distinguished by the club-shaped form of its lower side-teeth, and 

 by the total absence of a cleft in the glenoid border of its coracoid. 

 Anarosanrus (as the new genus is termed) is also distinguished 

 from Lariosaurus by its dentition, and difi"ers from the type species 

 of the latter in the sleuderness of its ribs and femur, and in the
