84 ON A NEW GENUS OE THE EAHILY LIPAEID^. 



our coast." Several European species of fisli have beeu found 

 existing in more or less plenty in that portion of the world and in 

 Tasmania — as Chondropterygian fishes destitute of air-bladders, 

 and Scicena abulia, Zeus faber, and Trachurus trachurus (species 

 with the air-bladder of the Physoclisti type), all of which, we might 

 perhaps imagine, could work their way " sub mari "in a colder 

 stratum of the water. But Glupeasprattus and Engraulis encrasi- 

 cliolus (var.), physostomous surface-swimming European forms, 

 have likewise been taken in Tasmania ; and it does not seem cre- 

 dible that such forms would live at great depths in the tropics and 

 travel in safety through the warmer regions of the globe, to pass 

 from the North Atlantic to the South Pacific ocean. Whatever 

 the explanation may be, the fact remains ; and to the European 

 forms of fish which have been recorded as existing in the anti- 

 podes, the Argentina sphyrcena must be added. 



[Since the foregoing 'paper was read, Professor GHglioli has 

 published the following remark in his ' Catalogo degli Anfibi e 

 dei Pesci Italiani,' under the head of Argentina spliyroena : — " Won 

 frequente, ma neppure rara ; cosi sul mercato di Eoma nel gen- 

 naio 1879 ne ho veduto ceste piene. Credo poter affermare che, 

 se basata sulla mancanza di denti linguali, YA. lioglossa, C. e V. 

 va cancellata, giacche nella serie raccolta a Messina si vede ogni 

 possibile gradazione nelle sviluppo di quei denti ed alcuni esem- 

 plari ne sono privisenza per altro difterire dagli altri."]

Description of a new Grenus of Moth of the Family Liparidce 

 from Madagascar. By Arthur G. Butler, E.L.S., P.Z.S., &c. 



[Eead April 1, 1880.] 



The following new genus was received last year in a collection 

 made by Mr. Shaw at Eianarantsoa, Madagascar ; but I had at 

 the time so strong an impression that I had somewhere seen 

 a figure or a named example of the species, that I hesitated to 

 describe it : it is probable that I had in my mind the New-World 

 genus Megalopyge of the family Lasiocampidre, which bears a 

 vague resemblance to it in some respects. I now have no doubt
