Show Artemta Utahensis. A very intcri'sling met-ting of the San Francisco microsmpiral society, was held in that city l;it Thursday evoning. The Alia publishes the minutes of tho meeting, from which we observe that Dr. Hnrkuess exhibited exhi-bited what proved to be an undes-cnhetl undes-cnhetl species of ai tcmia, which was found near the middle of Great Salt Lake, Utah, upon and near the surface, sur-face, by Mr. Henry Harkncsa, and upon which Mr. W. N. Lockington, of San Francisco, presented the following fol-lowing paper: A PHYLLOI'OD crustacean. A phyllopodus crustacean from Great Salt Lake, Utah, nearly allied to the artatuii salina, which inhabits tho salt pans in which brine is undergoing under-going concentration, and n louud at Lymington, England, and oilier places, was presented to mo by Dr. Hark nets, to-day, for examination. I take greal pleasure in submitting a description descrip-tion ol tho bame. The inferior antenna;, anten-na;, in the male, are two jointed. Tne casal joint, with a s'.iort rounded process pro-cess (in artemia sahna this is conical ); the joint itself thick and rounded; the second and terminal joint broad and. fan-siiaped, aud the whole an'.enmo1 'somewhat resembling the mandible of a stag beetle in general appearance; appear-ance; llio inferior antennas in the mate, ajd both pairs in the female slender and piliform; the thorax willi eleven pairs of branchisc ; eyes on SllOrf. rwvllln.'lpd iltulnivmti ni'nn. jointed; tho end joint two-lobed, each! lehe bearing a variable number of actio (4 G); color, a dark purplish brown. From the locality in which it was collected, it is proposed to name the species Ar tenia C take ash. Everyliody here knew those insects were in the lake, but it never occurred occur-red to any one in this region that they were of so much importance, and were so fearfully and wonderfully made. Our townsman, Mr. Henry Harkness, is entitled to a great deal of credit for his share ol the discovery of those patent levered, double-jointe I, piliform antenms, theel-.veu pairs of branchicB, that abdomen with its nine-jointed, two-lobed variable sct;e. Of course he will take no honor fur the "mandible of the stag bje'.!o,' which is nothing more or less thaa the denticulated and furcated organ or-gan which projects from tho caput of the coleopterous invertebrate, of the articulate division of tho anim d kingdom, knowu as tho luzawis CCf cos. |
