Excerpt from The Journal of the Linnean Society, Vol. 10: Zoology Having taken all the members which constitute this interesting group, I am enabled to say that, in general aspect, the present resembles Thompson's Midge more than any of the others - also that in length the pectorals and ventrals approximate much nearer to that species than to any of the rest. In attempting, however, as I have done, to give the formula of the fin-rays, &c., I would crave a little indulgence for, although several specimens were examined, both dead and alive, the task, from various circumstances, proved a rather difficult one. Still I think that most of the numbers stated will be found, if not altogether correct, at least pretty close to the mark and, although of no other value, they may serve as a guide to others, until some one else, gifted with more patience, possessed of better discerning powers and a clearer vision, attempts the task, and gives them more correctly, should I be in error.
