298 SIR V. BROOKE ON CERVUS MESopoTAMicus. [Mar. 7, 



yelk-contents into two masses, the smaller division being finely gra- 

 nular, whilst the larger mass was formed of moderate-sized corpuscles 

 like those usually seen in the so-called mulberry-cleavage stage. 



19. Strongylus TUBiEFORMis, 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 Httle 

 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 ofthe Royal Veterinary College), I did not make a very 

 full examination of the worm; but on referring to my 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 | of an inch. As it is the only speci- 

 men that has come under my notice, I have figured it (fig. 20).

4. Supplemeiitaiy Notes on Cervus mesopotaraicus. 

 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 

 thehoxwi o^ Cervus mesopotamicus (videV. Z. S. 18/5, p. 261, pi. 38), 

 I hasten to lay before the Society some additional observations which 

 these specimens have enabled me to make upon this interesting 

 species.
