General Remarks and Faunae. 
Dr. Gunther directs attention to the fact that in numerous groups of 
fishes which live in mud, forms occur entirely devoid of, or with only rudi- 
mentary, ventral fins. Ann. & Mag. Nat. Hist. xx. p. 308. 
In order to ascertain the cause of death of marine fishes transferred into 
fresh water, M. Bert made a series of experiments. He dissolved sugar in 
the water, so as to render its density equal to that of sea- water ; the fishes 
introduced into this solution survived for a considerably longer period than 
others brought into pure water. Ann. Sc. Nat. 1867, ‘vdi. pp. 369-371. 
M. CosTE, Compt. Rend. 1867, January 21, pp. 99, 100 (Ann. & Mag. Nat. 
Hist. 1867, xix. p. 227), directs attention to a large marine reservoir at Con- 
carneau, in which the conditions of the open sea are so well imitated that 
a female IScyllium catalus deposited her eggs, which were hatched. 
Great Britain. Dr. Gunther has reported on sotne fishes collected by Mr* 
J. Gwyn Jeflreys in the sea of the Shetland Islands (not Hebrides, as erro- 
neously stated in the paper) at a depth of 80 or 90 fathoms. The four 
species, Ammodytes sicidus (Swains.), Motella macrophthalma, sp. n., Callio- 
nymus maculatm (Bonap.), and Gohius jef)'eysii, were new to the British 
fauna. He adds some remarks on deep-sea fishes generally. Ann. & Mag. 
Nat. Hist. XX. pp. 288-291.
