Remarks. 



Leach was the first who made a group of Gamasus-\\ke 

 animals ; the group is called by him Gamasides in the Transactions 

 of the Linnaean Society of London, of 1814. The same denomi- 

 nation is used by Sundevall in h\s Conspectus Arac /midiim,iS33, 

 by Koch in his Uebersicht des Arachnidensystems , III , p, 80 , 1842 , 

 and by Andersen in Oefv. Kong. Vet. Akad. Forh. 1863, p. 185, — 

 A second name for this group was proposed by Duces, in 1834, 

 viz. Gamasei (Ann. Sc. Nat. (2) II, p. 18). — Subsequently we 

 have the following synonyms: 1849, Gamasea v. d. Hoev. , Hand. 

 Dierk p. 670. — 1851 , Gamas'ma Grube in Middendorf's Sibirische 

 Reise p. 37 , followed by Gerstaeker in his Handbuch der Zoologie 

 p. 343 (1863). — 1855, Gamasìàae Nicolet in Achiv. du Mus, 

 VH, p. 383, followed by Grube, in 1859, in Arch. f. Nat.Liv., 

 Ehst., u. Kurl. (2) I, p. 434, 459; by Giebel, 1863, in his

 Beneden, 1869, in their Zool. med. II, p. 455, by Harting ,
