FISHES 



1 66. Xope. Galeus vulgaris, Flem. 

 Not uncommon. 



167. Hammerhead. 'Lygesna malleus, Risso. 

 A specimen is recorded as taken at New- 



lyn in 1834. 



1 68. Rough Hound or Small-spotted Dog- 



fish. Scyllium canicu/a, Linn. 

 Very common. 



169. Nurse Hound or Large-spotted Dog- 



fish. Scyllium catu/us, Cuv. 

 Common, but not so abundant as the pre- 

 ceding. The eggs of this species are found 

 attached to stems of Laminaria at low tide at 

 St. Just in Falmouth Harbour. 



170. Black-mouthed Dog-fish. Pristiurus 



melanostomus, Bonap. 



One specimen 25! inches long was taken 

 at Polperro in 1834. 



171. Smooth Hound. Mustelus vulgaris, 



Mailer & Henle. 

 Common. 



172. Porbeagle. Lamna cornubica, Gmel. 

 Has been frequently taken. Dunn re- 

 corded a pair taken at Mevagissey in 1881, 

 the male 9^ feet long, the female 8 feet. 



173. Thrasher. Alopias vulpes, Gmel. 



Not uncommon. Is frequently captured by 

 the mackerel or pilchard nets. A specimen 

 was landed at Cadgwith about the year 1900, 

 and the writer has seen it leap clear above 

 the surface of the sea off Falmouth. Mr. 

 Gatcombe records one 5 ft. 6 in. long taken 

 at Mevagissey on a common whiting hook. 

 In 1878, according to Mr. Dunn, the crew 

 of a trawler reported that they saw a thrasher 

 and a sword fish attacking a rorqual in Meva- 

 gissey Bay. 



1 74. Basking Shark. Selache maxima, Gunn. 

 A specimen brought ashore in Cornwall 



and described in J. Couch's British Fishes 

 measured 31 ft. 8 in. in length. A specimen 

 landed in St. Austell Bay near Menabilly, 

 the seat of the Rashleighs, was 29 ft. 4 in. 

 long, had a mouth 2| feet wide and weighed 

 4 tons. The peculiarities of the head of this 

 specimen as shown in a drawing given to 

 Couch led him to describe it as a distinct 

 species under the name Polyprosopus rashleigh- 

 anus,.but later authorities consider it to have 

 been Selache maxima. A specimen 9 feet long 

 was taken in Mount's Bay in 1870 (Cocks, 

 Corn, Polyt. Sac. 1870). 



175. Six-gilled Shark. Notidanus griseus, 



Gmel. 



In May 1873 one i\ feet long was taken 

 by baited hook three miles offshore at Meva- 

 gissey. In 1846 one 26 ft. 5 in. long was 

 captured at Polperro, and another 6 feet long 

 taken at the same place is in the British 

 Museum. 



176. Picked Dogfish or Spur Dog. Acan- 



thias vulgaris, Risso. 



Abundant ; sometimes swarms in such 

 numbers as seriously to interfere with the pil- 

 chard and mackerel fishing. At Mevagissey 

 a year or two ago I saw a large number being 

 cleaned and prepared to be sent to market for 

 eating. It is viviparous. 



177. Centrina salviani, Risso. 



A specimen was obtained by Mr. Cornish 

 in 1877 which had been trawled near the 

 Wolf Rock. 



178. Spinous Shark. Echinorhinus spinosus, 



Gmel. 



A large number of captures of this species 

 in Cornwall have been put on record : one 

 8 feet long in 1849 by Cocks at Falmouth ; 

 a female 7^ feet long on a line at Polperro in 

 1867 ; in 1 88 1 one 6 feet long was caught 

 sixteen miles off the Deadman. Mr. Cornish 

 recorded five taken in Mount's Bay between 

 1865 and 1881. 



179. Angel-fish or Monk-fish. Rhinasquatina^ 



Linn. 



Common. Taken sometimes in trammels 

 and cut up as bait for crab-pots, also trawled 

 and caught on long lines. It is often 5 or 

 6 feet long, and is said to reach even 8 feet. 



1 80. Torpedo. Torpedo nobiliana, Bonap. 

 Has frequently been captured. Couch 



alludes to five taken in one year in Mount's 

 Bay, and two or three which came under 

 Cocks' observation at Falmouth. T. Cornish 

 records one trawled in 1873 between the 

 Lizard and Land's End, and a second near 

 Penzance. In 1881 specimens were taken at 

 Pen/ance, St. Ives, Falmouth, Polperro and 

 Mevagissey. In the Report of the Penzance 

 Nat. Hist. Sac. 18834 two are recorded as 

 captured in a ground seine at Porthleven.
