Miscellaneous. 321 that its eggs are unknown, he proceeds to describe the eggs of a widely different Nearctic species, the Spine-tailed Swift, and remarks that he has " reason to believe that eggs of this species are passed off by some dealers for those of the Needle-tailed Swift " {A. caud-acuta) — a statement which, if correct, merely tends to show how very easily mere egg-collectors are imposed on by unscrupulous dealers. No care appears to have been exercised in selecting the proper scientific names, either generic or specific, in accordance with the generally accepted rules of synonymy ; and one finds therefore the Killdeer Plover rejoicing in the generic title of Oxyeclius, the Spotted Sandpiper in that of Trin()oicles, and the Solitary Sandpiper in that of Khyacophilus, whereas, on the other hand, both the Yellow-legged Sandpiper and the Bar-tailed Godwit are classed under Totanus. At pp. 91 and 92 lists are given of the doubtful species which the author considers should be admitted in or excluded from the British List ; and here we fail to see, judging from the evidence on record, why Buteo lineatus, Coracias leucocephalus, Colaptes auratus, Churadnus viryhiicus {dominicus), Podilymhus podiceps, &o. should be admitted, and Emheriza pusilla, Emberiza melanocepJiala, Motacilla viridis, &c. excluded. Many other comments and criticisms occur to us as we glance through the pages of this List, but we think that it will be useless to weary our readers with further remarks. At the end of the List (pp. 97-148) " a few remarks on evolution " are given, and (pp. 150, 151) a " compendious scheme of Keconcilia-tion between the Earth's Kecord compiled in the Nineteenth Century and the Divine llecord delivered to Moses " is given in tabular form ; and here, again, we can offer no further comment than that we think it would have been better both for the author and his readers had he studied the subject a little more closely and digested the vast amount of available material before committing his ideas to paper. MISCELLANEOUS. On a new Parasitic and Nldulant Rhahdoccelan (Fecampia erythrocephala). By M. A. Giaed. The curious TurbeUarian which forms the subject of this note is very common on the shores of Fecamp and Yport. During a part of its existence it lives parasitically in Decapod Crustacea of various species — Carcinus moenas, Platycarcinus pagurus, and Pagurus Bernhardus. Carcinus moenas is the most commonly infested, but only when it is young ; to find the parasite we must open crabs from -^ to ^ inch broad. The grey or blackish colour of the cara-pace reveals almost with certainty the presence of the Fecampia. Ann. & Mag. N. Hist. Ser. 5. Vol. xviii. 22
