Show 298 SIR V. BROOKE ON CERVUS MESOPOTAMICUS. [Mar. 7, yelk-contents into two masses, the smaller division being finely granular, whilst the larger mass was formed of moderate-sized corpuscles like those usually seen in the so-called mulberry-cleavage stage. 19. STRONGYLUS TUB,EFORMIS, Zeder. (Plate XXI.) In the small collection of parasites presented to me many years ago by Mr. Caleb B. Rose, F.R.C.S., I only recently noticed a little nematoid which is clearly referable to this species. It was entangled amongst a number of characteristic examples of Ascaris mystax of the Cat, and had consequently been overlooked. Being a solitary male specimen (since added to the special series of Entozoa contained in the Museum of the Royal Veterinary College), I did not make a very full examination of the worm; but on referring to m y notes made on the 3rd of December last, I find that I have remarked upon the great size of the bursa, the rays of which were very conspicuous. I did not uncoil the specimen (represented in the accompanying Plate exactly as it appeared under Ross's •§" objective), for fear of injuring it; but I judged the length to be about f of an inch. As it is the only specimen that has come under m y notice, I have figured it (fig. 20). EXPLANATION OF PLATE XXI. Pig. 1. Ascaris cornelyi: head of female, magn. 20 diam. 2. The same: tail of female, magn. 24 diam. 3. The same : tail of male, magn. 25 diam. 4. The same: tail of a rather smaller male. 5. Strongylus hemicolor : male, magn. 30 diam. 6. The same: section of surface, magn. 150 diam. 7. The same : part of bursa, magn. 150 diam. 8. The same: head of male, magn. 150 diam. 9. The same : tail of female, magn. 30 diam. 10. The same : three eggs, magn. 150 diam. 11. Spiroptera muriei: head of male, magn. 30 diam. 12. The same: tail of male, magn. 30 diam. 13. The same: tail of female, magn. 30 diam. 14. Ascaris andersoni: tail of male, magn. 25 diam. 15. The same : tail of female, magn. 25 diam. 16. Oxyuris obesa : head of female, magn. 23 diam. 17. The same : tail of female, magn. 24 diam. 18. The same : tail of another female. 19. The same: egg, magn. 122 diam. 20. Strongylus tubceformis: male, magn. 23 diam. 4. Supplementary Notes on Cervus mesopotamicus. By SIR VICTOR BROOKE, Bart., F.Z.S. [Received January 19, 1876.] Having lately received from my indefatigable correspondent Mr. Robertson, H.B.M. Vice-Consul at Busrah, several fresh specimens of the horns of Cervus mesopotamicus (videP. Z. S. 1875, p. 261, pl.38), I hasten to lay before the Society some additional observations which these specimens have enabled m e to make upon this interesting species. |
