Hist. ser. 4, vol. iii. p. 19. n. 5, pi. 9. fig. 5 (Jan. 1, 1869), vol. vii. p. 447(1871). 3 • 1 Diadema formosa, Herrich-Schaffer, Stett. ent. Zeit. p. 71. n. 16, pi. 4. fig. 17 (Jan.-March 1869). Totoya, Fiji (Butler) ; Vanua Valava (Herrich-Schaffer). W . F. Kirby, in the 'Zool. Record' for 1871, states that if my D. octocula is^=D. formosa, the latter specific name will take priority. Upon what grounds he comes to this conclusion I am unable to imagine ; for it must be manifest to every reasoning being that the Jan.-March number of the ' Stettiner Zeitung' can only have been procurable on the 1st of April at the earliest, whereas my paper appeared on the 1st of January. 49.
