106 DR. W. BAIRD ON THE GEPHYREA. [Feb. 13, 



it not for the author's descriptions/to induce one to suppose that they 

 referred to a distinct species from the animal figured by Ehlers and 

 others, and tlie specimens from Scotland and Greenland which we 

 possess in our Collection. The P. hibernicus of INI'Coy, as figured 

 by him in the ' Annals,' exactly corresponds with the figure given by 

 Ehlers of P. caudatus, and with our specimens of that species in the 

 Collection as corrugated by the spirits in which they have been pre- 

 served. I have no hesitation, therefore, in referring it to our P. 

 caudatus. "What Quatrefages could see in either M'Coy's description 

 or figure to induce him to place it in the genus Lacazia I am at a 

 loss to understand. Indeed he himself places it there with doubt. 

 Linnaeus, in his dissertation, ' Chinensia LagerstrcEmiana ' (first pub- 

 lished in 1754), and afterwardsin the 'AmoenitatesAcademicae,' vol.iv. 

 p. 255, and in the 10th edit, of the Syst. Natur. p. 656 (1758), de- 

 scribes a species of Priaptdus which has been usually quoted as 

 synonymous with the P. caudatus. He names it in these works 

 Pi-iapus humanus — an objectionable name in itself, and which he 

 afterwards changed in the 1 2th edition of the ' Systema Naturae ' to 

 Holothuria priapus. As the species of plants and animals mentioned 

 in that dissertation ('Chinensia Lagerstroemiana') chiefly refer to those 

 inhabiting the Southern or East-Indian and Chinese seas, and as in 

 the 10th edit, of the Syst. Nat. he mentions distinctly the habitat " in 

 mari indico,^' I have some hesitation in referring the species described 

 there to the caudatus, which is a northern species, and not likely to 

 be met with in the Indian seas. Osbeck, however, a pupil of Lin- 

 naeus, mentions a species as found in China, and which is referred to 

 the Holothuria priapus of Linnaeus. His voyage to Cliina was made 

 in the years 1750-52; and an English translation, with a ' Faunula 

 Chinesia' attached, was published in Loudon in 1771 : vide this 

 edition, p. 337.
