 On p. 35 he tells us, " Squillaruni maris haltliici non nisi duos, ad summum, si saUatricem con- 

 numeraverimus, tres habemus species." The first two, Squilla fusea and Squllla ctnerea 

 (" An, sqvilla parva Rondeletii 1 ") are Podophthalma ; the third is thus described, p. 36, 

 " Sqvilla saltatrix ; Sqvilla parva, qure major nunquam effici potest, Wottonns fol. 207.

 accuracy of the figures. The short upper antennas make it clear that we have to do with 

 Orchestidfe. Fig. c rather points to a Talitrus. No dilated hands are shown in any of the 

 figures. 



1745. Linnaeus.

He describes Cancer fidex fluviatilis, p. 96, which he found on the strand at Oeland. 

 Erom the mention of oblong red blotches on the sides of the segments, Boeck conjectures 

 that this may be Gammanis marinus. Bate and "Westwood, it may be noticed, regard the 

 red spots on the sides as a distinguishing mark of Gammarus locusta, Brit. Sess. Crust., 

 vol. i. p. 380. The Cancer macrourus coeruleus thorace articidafo, p. 260, which Linnaeus; 

 found on the shore in Gottland, may in Eoeck's opinion be Gammarus locusta. Hans. 

 Strom, in 1765, expresses the opinion that Linnaeus has here given two descriptions for one 

 species. Bate and Westwood and Boeck alike refer to the coe^-uleiis species of p. 260 as a 

 synonym of Gammarus locusta, while the species of p. 96, with the red blotches, is not 

 given as a synonym of any species either by Boeck or the other authors. The observation of 

 Bruzelius, that Gammarus locusta is the only species of Gammarus which occurs in Gott- 

 land, is a negative argument on which but little stress can be laid. 



1746. LlNN^US.

The two last species of the genus Cancer are thus given : — 



"1253. Cancer macrourus rufescens ; thorace articulate. Eaj. ins. 44. Pulex fluviatilis. 



Frisch. germ. 7. p. 26. t. 18. Vermis aquaticus cancriformis. It. oel. 42, 96. Cancer 



Pulex fluviatilis dictus. Habitat ad littora maris vulgatissimus. 

 "1254. Cancer macrourus caeruleus ; thorace articulato. It. gotL 260. Habitantem vidi ad 



montem Tliorshurg in mari juxta Gotlandiam. Obs. Praecedenti major : totus cteruleus, 



rostrum nullum prominens, corpus 14 articulis. cauda trifolia; intermedio subulato." 

 Both of these, in Boeck's opinion, refer to Gammarus locusta, the references to Eay's and
