70 CORRESPONDENCE OF THE 



bad preservation, but much at your service. It seems un- 

 doubtedly of the Grallce Ordo. Hirundo rupestris was ob- 

 served by me in the winter months as long ago as the year 

 1758, by Scopoli in the summer, about the year 1767. Co- 

 turnix tridactylus must without doubt belong to the Ordo of 

 Gallince; possibly its legs were stretched too much in drying, 

 and thereby made it resemble one of the Ordo of Grallce. It 

 differs from one in the i Planches enluminees,' and, I hope, is a 

 nondescript species; if so, be pleased to honour it with a 

 specific character. 



Motacilla tithys is the Grey-redstart of Edwards, and the 

 Rutidlla gibraltariensis, No. 16, of Brisson. 



Piscis novus, capite excoriato, reticulato, cselato ; as you 

 esteem it a new genus, demands likewise a generic, as 

 well as a specific, name, from the great father of Natural 

 History. 



Coryphcenoides rupestris not appearing in the i Systema 

 Naturae,' Mr. Pennant gave it that name from Gunnerus. I 

 have more specimens, of which I will send you the best. 

 They are all found mutilated, being never taken alive in nets, 

 but cut out of the stomach of Squalus acanthias. Perca 

 dipterygia rubra appeared to me rare and doubtful. You 

 will best ascertain its proper titles. 



Cancer arctus * is, I suppose, Squilla ccelata, Rondeletii. 



C. carinatus"\, videN. 16, Brunnichii spolia maris Adriatic!. 

 C. antennis longissimis is certainly a distinct species. It's 

 colours beautiful. C. rostro longissimo must also be a peculiar 

 species. I have many specimens. C. brachiis hirsutis is 

 found in vast abundance under loose stones on the sea shore. 

 None larger than those which I sent you. 



These four want Linnsean names. 



ScarabcKus hispanus is sometimes found inclosed in a hard 

 oval ball of dung and sand mixed, through which, when 

 moist, it works its passage with its horn. Does it undergo 

 all its transformations in this prison? Mantis gongylodes
