which was provided with a sort of cap, and the posterior 

 with a short aiid a long point, are described by Rolando as 

 Cucullani ; they were besides encircled anteriorly with a 

 reddish ring, from which a black stripe ran backwards, the 

 whole length of the body. A nematoid worm, found in the 

 abdominal cavity of Corvus graculus, which possessed a 

 bilobed mouth, and was equally thick and rounded at either 

 end, he refers to the genus Filaria, as well as another worm 

 from the abdominal cavity of Turdus saxatilis, with depressed 

 body and a toothed caudal extremity. The viscera pro- 

 truding from the ruptured body of this worm appeared to 

 him "mi fenomeno molto singolare." In consequence of 

 this rupture, undoubtedly, the caudal extremity was entirely 

 curled up, and was viewed by Rolando as being toothed. 

 He, moreover, found in the lungs of Ardea purpurea various 

 intertwined aggregations of nematoid worms, which reminded 

 him of the Hamularia of Treutler, but as he did not remark 

 at one end of the body any hook-shaped appendage, he 

 referred them to Cucullanus. A headless T&nia, from the 

 intestinal canal of an Ardea major, has been most imper- 

 fectly described. A nematoid worm, parasitic in the intes- 

 tine of Ardea uycticorax, has been named by Rolando, on 

 account of its long rostellum, Proboscidea, but it is most 

 probable that he has taken the slender caudal extremity of 

 the worm for a rostellum. Of two EchinorhyncM, from the 

 intestinal canal of Mursena anguilla and Cyprinus carpio, the 

 latter is said to have had no booklets on the rostellum. 

 Several worms, four lines in length, which inhabited the 

 muscles of the head of Esox lucius, have been described as 

 LinyuatulfB, because they are said to be furnished at the 

 anterior extremity with four to five pores. A similar smaller 

 species of Linguatula was observed in the dorsal muscles of a 

 Cyprinus tinea. 



Lastly, Rolando has noticed another Echinorhynchus from 

 the intestine of Falco pygargus, and some worms from a 

 species of Moth (Nachtfauenauge) from a Cerambyx, a 

 Limax, and a Sepia, but which he had not examined more
