382 THE ZOOLOGIST. 



the gill-cover and pectoral fin two inches and a quarter. The lower border 

 of the gill-covers of the left side overlap the corresponding portion of the 

 right. The body is covered with moderately small scales, which were easily 

 removed for the most part when the fish was caught. The lateral line 

 begins even with the upper border of the hindmost gill-cover, and passes 

 straight to the middle of the tail. The first dorsal fin begins five inches 

 and a half from the snout, and consequently is nearer the caudal fin than 

 to the point of the upper jaw ; its posterior border incurved, as are those 

 of the second dorsal and anal ; both the last-named near the tail, their 

 posterior portions so low as to be scarcely perceptible, and even the anterior 

 portion of the second dorsal very slight. Ventral fins under the first dorsal ; 

 the tail rather wide, incurved, the anterior border of it above and below 

 narrow and almost touching the lower rays of the second dorsal and anal. 

 Where the scales remain and on the cheeks the colour is bright, with a 

 tinge of blue, a little darker on the back, but where the scales are gone, 

 as they are for the most part, the whole is brownish black, and along the 

 lateral line are a series of triangular spots or marks. In its perfection the 

 surface probably is brilliant. Mr. Dunn informs me it was found alive at 

 Polkerris pier, and was caught with the hand ; it was thought to have been 

 wounded by another fish. He says: — 'The sides presented an uniform 

 silvery brightness, but the scales were so delicate that they at once came off 

 on the hands when touched. When it came to me the point of the snout 

 from the eye was injured. The eye was bright.' I find in my edition of 

 Cuvier (not Griffiths') a figure of P. coregonoides ; that two species are 

 figured, but the P. coretjoiioides has a particular marking on the hindmost 

 gill-cover, not seen in my example, but this may be explained by the fact 

 that the skin of that part was gone, and the lateral line of my example was 

 unlike that of the other figure as copied from Risso." — Fkancis Day

Lamprey in the Wear. — A specimen of Petromyzon fluviatilis was 

 caught in this river, near Finchale Abbey, last July. It measured about 

 fourteen inches in Length, and from its condition was evidently spawning at 

 the time of being caught. There were from ten to twenty others in 

 company with it. As far as 1 can understand, this is the only specimen 

 which has been taken so far up the river, if taken in it at all. Dr. Tristram 

 purchased it from the party by whom it was caught. — J. Ouj,lingfokd

Parasitical Worms in a Hornbill. — With this I send you some sub- 

 cutaneous worms which I found in a young Hornbill — either the Elate 

 Hornbill, Buceros elatus, or Black Hornbill, B. atratus. There were a 

 considerable number of them, especially between the pectoral muscles.
