proper name both by Ovid and Pliny, and therefore not to be put in a 

 feminine shape. 



The present species is, I think, the glaucus of Rondeletius, and 

 therefore the Glaucus secundus of Ray, p. 94. 



The Lichia Amia of Cuvier is the Scomber Amia of Linnaeus and 

 Amia of Aldrovandus and Ray. The glaucus of Cuvier has a charac- 

 teristic figure in his great work i Icthyologie,' but the only other species 

 he mentions is Lichia Vadigo, a native also of the Mediterranean ; it 

 has a longer body and a shorter tail than L. glaucus. It is true he 

 has another species, but that belongs to the Coast of Africa. 



I have been favoured with coloured tracing of two figures, from Col. 

 Hamilton Smith, of Lichia glaucus, and this, by comparing the coarse 

 wood-cut of Rondeletius with the recent n\sb, enables me to identify 

 the species ; but coarse as the cut is, it is very characteristic : he 

 says, however, that the moustache is rough ; in my specimen it is 

 smooth. 



The difference between this description of Rondeletius and the 

 specimen I have in my possession is so small that there can be no 

 doubt that he refers to this species.

Occurrence of the Black Fish (Centrolophus pompilus, Cuv.) in Mount's Bay. — 

 A small specimen of this fish came into my possession last autumn twelve months, 

 which was captured in a mackerel seine, in Groavas Lake, in Mount's Bay : it was 

 nine inches long, and presented all the markings of the larger specimens which I have 

 examined. — R. Q. Couch; Penzance, December 7. 1858. 



Correction of an Error. — In the ' Zoologist,' (Zool. 5959) is a notice of the capture 

 of Notidanus griseus, " a shark new to Britain, at Banff," by Mr. Edward; but if you 

 will turn to Vol, iv. for 1846, p. 1337, you will there find it both figured and described, 

 and I sent the MS. to you. Excuse my reference to the subject, but I thought it an 

 oversight, and would remind you of it. — Id. 



Abundance of Colias Edusa in 1858. — In June I took two very fine females and 

 saw a third ; in August and September the insect was very plentiful, and I took a 

 great many, likewise five of the white variety : on the 15th of October, being a fine 

 warm day, it was flying in great numbers on Norton Common, close to the sea ; I had 

 no net with me but I succeeded in capturing, with my hat, a fine white variety of it, 

 which makes the sixth taken by me this season, and on Sunday, the 7th of November, 

 I saw one very much worn : I should like to know if they have been seen in any 

 other place so late as this. — H. Rogers; Freshwater, Isle of Wight, December 1, 1858.
