230 DESCRIPTION OF A NEW srECIES OF LAMIA. 



scribed, and I have referred it to the genus Anthocephalus, (as 

 in a former paper I did that which I named Anth. paradoxus), 

 not on account of its agreeing exactly with the character of 

 that genus, for it has no caudal vescicle, but because it ap- 

 proaches more nearly to it than to any other. Much, I be- 

 lieve, must yet be known concerning the encysted Entozoa, 

 before a proper arrangement and nomenclature can be applied 

 to them ; and in the mean time it is perhaps better to refer 

 them to known genera, at the risk of some inaccuracy, than to 

 fabricate new names, which, after a time would, in all pro- 

 bability, have to make way for others of still newer coinage. 

 The specific title, rudicornis, I have applied on account of 

 the coarse appearance of the rostella as compared with that 

 of any others which I have hitherto observed. 



The only other Entozoon which I observed in this large 

 halibut was the Filaria capsularia, which, in great numbers, 

 lay coiled up in the peritonaeum of the stomach, liver, and in- 

 testines. But, however copious they might be in these loca- 

 lities, still the number was small when compared with that 

 which I detected between the middle and inner coats of the 

 stomach. The former, or muscular coat of this viscus, in the 

 halibut, is connected with the inner or mucous coat, through- 

 out a great part of its extent, by a thick, lax layer of cellular 

 membrane ; and on separating the one coat from the other, I 

 found this layer to be, in many places, literally crammed with 

 the FilaricB. They were in hundreds, each rolled up singly 

 in a spiral form, but more frequently with several others 

 under the same covering, forming so many distinct, round, 

 flattened masses, lying as close to each other as stones in a 

 pavement.

Art. V. — On a new Species of Lamia from the vicinity of the Swan 



River, New Holland. By The Rev. F. W. Hope, F.R.S., 



F.L.S., &c, &c, &c. 



I send for insertion in your c Magazine of Natural History, 1 

 a description of a new species of Lamia from the vicinity of 

 the Swan River, in Australia. My chief object in selecting 

 Lamia is in consequence of the Baron De Jean, in his last 

 Catalogue, omitting that term altogether, while he coins and 

 publishes a new name to include under it insects which have 

 years ago been ably described by the celebrated Fabricius. 

 If entomologists of the present clay are allowed to expunge,
