46 THE NAUTILUS. 



Two species of Spondylus are contrasted and are named respec- 

 tively S. mediterraneus and S. americanus (Der Naturforscher XVI, 

 1781, p. 51). The former is evidently S. goederopus Linn6. The 

 latter must be the common spiny species of the West Indies com- 

 monly known as S. americanus Lamarck, for which Doctor Dall 

 (Trans. Wagn. Inst. Ill, part iv, 1898, p. 759), after a consideration 

 of the extensive synonymy, adopts the name S. echinatus Martyn, 

 1784, which apparently should now give place to S. americanus 

 Hermann, 1781. 



Turbo canaliculatus, Hermann. 



Der Naturforscher, XVI, 1781, p. 52, PI. ii., fig. 1. 



This species is clearly the ordinary large Turbo of the "West 

 Indies, usually known as T. spenglerianus Gmelin. The latter 

 author, though he cited Hermann's work (Syst. Nat., xiii, 1790 p. 

 3571), made the double error of using his name in another sense and 

 of bestowing a subsequent name upon Hermann's species. Both the 

 species termed Turbo canaliculatus by Gmelin and Kiener respec- 

 tively, are Oriental. 



Nekita cancellata, Hermann. 



Der Naturforscher, xvi, 1781, p. 56, pi. ii, fig. 8. 9. 



Here again Gmelin has misunderstood the work of Hermann. 

 After quoting (p. 3670) the above reference, he adds from Chemnitz 

 accounts of two distinct shells, the one Natica sulcata Born, a West 

 Indian Natica, the other Vanikoro cancellata, Lamarck. In his turn 

 Lamarck was thus led to confound these species, a confusion which 

 was unraveled by Deshayes, (An. s. vert. [2] viii, 1838, p. 644). 

 Hermann's illustration well represents Nerita sulcata, Born (Index 

 Mus. Caes. Vind., 1778, p. 416, PI. 17, fig. 5, 6), which is main- 

 tained by three years' priority. 



BucciNUM SOLUTUM Hermann. 



Der Naturforscher, XVI, 1781, p. 53, PI. ii, fig. 3, 4. 



Dr. W. H. Dall kindly gave us the benefit of his wide knowledge 

 of this boreal group. Hermann's figure appears to him to represent 

 a short form of Chrysodomus heros Gray (Proc. Zool. Soc. 1850, p. 

 14, PI. VII) a species erroneously united by Kobelt, Conch, Cab. 

 Fusus, 1881, p. 61, to Neptu7iea fornicata Gray non Gmelin. Her- 

 mann's name should therefore be maintained.
