While this edition was at prefs, fome information has been ob- 

 tained, by which it might have been amended in fome inftances, and 

 augmented in others. Thus, Camper, the greateft comparative ana- 

 tomift of the age, having lately an opportunity to diffect the Siren *, 

 has difcovered that, on each fide of the head, it is furnifhed with 

 three true gills, feparated from each other by membranes having 

 tooth like appendages; that the mouth is armed with ftrong and firm- 

 ly planted teeth; that the heart has only one ventricle; and that the 

 abdomen is filled with very long and capacious interlines: From all 

 thefe circumftances, he concludes thac this animal ought to be con- 

 fidered as a fifh of the order Branchioftegi ; while in other refpe&s 

 it is more nearly allied to the genus Murena, of the order sJpodes ; 

 although it differs materially from the other fpecies of that genus, 

 by having only three notched bones in the gills, and from the pecto- 

 ral fins being each divided into four finger-like appendages. 



Two apparently new fpecies of filhes, frequenting the mores of 

 the ocean near Bahus, have lately been difcovered, and defcribed in 

 the Stockholm Transactions, Vol. xii. ift quarter, No. 9. One of 

 thefe, which was found at Iihuedefholm, is by Ruchenfparr, named 

 Euprafes ; it is a fpecies of Gobius, about an inch long, and fpotted. 

 with black, having a diftincT: black fpot on each fide at the bafe of 

 the tail; the fecond dorfal fin has eight pointed, and eleven blunt 

 rays ; the firft dorfal fin feven rays ; the pectoral fins fifteen rays 

 each; the ventral fins, which are united, have eight rays; the anal 

 fin eight rays ; and the tail twelve : The other, which was found at 

 Kyrkefund, is a fpecies of Cottus, named Bubalis; it is brown on the 

 back, and has a white belly; it is fmaller than the Cottus J cor plus, or 

 feather-lafher; has a rough thorny head provided with two horns;

* The Siren lacertitia of the Linnaean, and Murena Siren of the prefent edition : 

 This animal, which lives in muddy places and feeds on ferpents, was lately defcribed 

 by Ellis in the Philofophical Tranfaftions, Vol. lvi. 189.
