Show 264 MR. P. L. SCLATER ON THE PELICANS [May 14, that of 8. sipunculiforme. I exhibit figures of both of these species, which will show the great differences between them. SCLEROSTOMA CLATHRATUM. Caput corpore discretum, cylindricum, parvum; oris limbo interno dentato, limbo externo auriculato; auriculis quinque; corpus utrinque attenuatum, lineare. Femina. - Corpus minute clathratum, striis exilibus transversis longitudinalibus; cauda obtusa, scepe convoluta, apertura genitali supra apicem. Mas.-Corpus longitudinaliter minute striatum, striis numerosis bursa caudalis lobata. Long. fem. lin. 26, lat. lin. 1. Long, maris lin. 24, lat. lin. 1|. Hab. In ventriculo Loxodontce africance. The head is distinctly separated from the rest of the body, and is cylindrical and small; the mouth is dentated inwardly, and on the outer edge is marked with five distinct auricles, which descend upon the upper portion of the body, but do not form a distinct part of it. The body is attenuated at both extremities and is linear in shape ; in the female it is, as it were, minutely clathrate, being striated transversely with fine lines, and having the spaces between the lines minutely longitudinally striated or sulcated, giving, under a tolerably high power, the appearance of being latticed or clathrate. The tail is obtuse, not so sharp-pointed as Sclerost. sipunculiforme, and has the genital organs situate a short distance from the extremity; it is frequently, but not in all cases, convolute. The body of the male is longitudinally striated, and the bursa at the extremity of the tail islobed. The African Elephant, from which these worms were taken, was a young female which died in London in October 1867. I am not aware of any entozoa having been previously described as inhabiting the body of this species of Elephant. 2. Notes on the Pelicans living in the Society's Gardens. By P. L. SCLATER, M.A., Ph.D., F.R.S., Secretary to the Society. (Plates XXV. & XXVI.) The Society's series of Pelicans has been much augmented of late years. During the present spring examples of no less than six distinct species have been exhibited, concerning which I beg leave to offer a few remarks to the Meeting. 1. PELECANUS ONOCROTALUS, Linn. Of this well-known species two fine examples, acquired in 1851 and 1852, are in the Society's collection. Early every spring thev |
