62 COOKE: NOMENCLATURE OF BRITISH NUDIBRANCHIATA. 



arhorescens (as pointed out by Dr. Norman) frondosus, As- 

 canius. The reference is : Ampliitrite frondosa, Ascanius, 

 Kon. Norsk. Vid. Selsk. Skr., v (1774), p. 155, pi. 5, f. 2. 



P. 63. Hero Formosa, Loven. — After "1844" i7isert "p. 49" 

 and dele the remainder. 



P. 64. LoMANOTUS MARMORATUS, A. and H. — The reference 

 has been omitted. It is: Eumenis marmorata, A. and H., 

 Ann. Mag. Nat. Hist., xvi (1845), P- 3ii- 



P. 66. ScYLLAEA PELAGiCA, Linnc. — The reference to the loth 

 ed. of 1756 (p. 656) takes the place of that to the 12th 

 (1766—68). 



P. 67. Tritonia HOMBERGii, Cuvicr. — For "Mem. du Mus., i, 

 p. 483, pi. 31, f. I, 2 " read "Ann. Mus. Hist. Nat. Paris, i 

 (1802), p. 483, pi. 31, 32." 



P. 69. Aegirus, Loven. — Read " Argircs" see Loven, Oefv. 

 K. Vetensk. Akad. Forh., i, 1844, p. 49. 



P. 70. Aegirus punctilucens, d'Orb. — The reference to 

 d'Orbigny, to be correct, should read " Mag. de Zool., vii 

 (1837), Classe V, p. 7 of memoir." 



P. 71. Triopa claviger, Muller. — No reference to any descrip- 

 tion by Muller is given, while that to an article by Johnston 

 is unnecessary. O. F. Miiller described the species in Zool. 

 Dan. Prodr. (1776), p. 229, pi. 17, f. i — 3. Johnston's 

 original description of Ter<ji2)es pulcher (the identity of which 

 with Miiller's species he afterwards recognised) was in Mag. 

 Nat. Hist., vii (1834), p. 490, f. 59. 



P. 73. Thecacera virescens, a. and H. — The original descrip- 

 tion was not, as here given, in the monograph, but in Ann. 

 Mag. Nat. Hist., 2 s. viii (185 1), p. 290. The reference to 

 A. and H.'s. appendix should be " p. iv" not "p. iii.'" 



P. 76. PoLVCERA LESSONi, d'Orb. — For " p. 5 " read " Classe v, 

 p. 5, of memoir," and for " Lessoni " read " Lessonii." 



P. 80. Idaeia pulchella, a. and H. — For "p. 19" read 

 "p. 46." 



P. 83. Doris tuberculata, Cuvier. — The reference is incorrect. 

 Read Ann. Mus. Hist. Nat. Paris, iv (1804), p. 469, pi. 74 

 (Doris pi. 2), f. 4. 



P. 85. Doris testudinaria, Risso. — For "p. 33, f. 15" read 

 "p. 33, pi. 2, f. 15." Bergh, perhaps rashly, identifies this 

 species with Arr/o, Linne. 



P. 86. Doris coccinea (Forbes), A. and H. — By " Rep. ^gean 

 Invert. B. A., 1843," is meant Rep. Brit. Ass., 1843, p. 133
