264 MR. 1'. L. SCLATER ON THE PELICANS [May 14, 



that of /S. sipunculifonne . I exhibit figures of both of these species, 

 which will show the great differences between them. 



SCLEROSTOMA CLATHRATUM. 



Caput corpore discretum, cylindricum, parvuni ; oris limbo interno 

 dentato, limbo externo auriculato ; auriculis quinque ; corpus 

 utrinque attenualum, lineare. 



Femiua. — Corpus minute clathratum, striis exilibus transversis et 

 longitudinalibus ; cauda obtusa, stepe convoluta, apertura genitali 

 supra apicem. 



Mas. — Corpus longitudinaliter minute striatum, striis numerosis ; 

 bursa caudalis lobata. 



Loug. fem. lin. 26, lat. lin. 1. 



Long, maris lin. 24, lat. lin. Ig. 



Hah. In ventriculo Loxodontce afrieance. 



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 

 is lobed. 



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 ou 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. & XXVL) 



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 they
