1873.] DR. T. S. COBBOLD ON NEW OR RARE ENTOZOA. 741 



I obtained very satisfactory evidence of the existence of a minute 

 terminal papilla, whose breadth scarcely exceeded the goVtr hich. 

 I have no doubt that this papilla is connected with a caudal gland ; 

 but I could not obtain a clear definition of the parts beneath the true 

 skin. Lastly, I may add that immediately above the bursa I noticed 

 a series of lines obliquely directed upwards, representing as many 

 parallel foldings of the integument. The general character of these 

 markings in all respects corresponded with the similar appearances 

 figured and described by Eberth in Enoplus, Enchelidium, and other 

 nematode geuera.

In the month of July of the present year I received from Mr. 

 Millen Coughtrey (then acting as Demonstrator of Anatomy in the 

 Liverpool School of Medicine) the heart of a Seal, together with a 

 communication, from which I further learn that Mr. Coughtrey was 

 himself indebted to Mr. T. J. Moore, the well-known Curator of 

 Sir William Brown's Museum, for the opportunity of dissecting the 

 animal in question. Mr. Coughtrey remarks that the Seal was an 

 adult male example of Stemmatopus cristatus, or Hoodcap, the oc- 

 currence of which is very rare on the British coasts. The animal 

 was captured in February at Frodsham, on the Cheshire side of the 

 Mersey, and died at Widnes in the beginning of June, having been 

 exhibited in the county during the interval. Mr. Coughtrey adds : — 

 " I made a hurried, but careful post mortem examination, since it 

 was suspected that it had died of poison. The dissection embraced 

 every organ except the brain and spinal cord. The abdominal 

 viscera were free from cysts or any appearance of worms. Within 

 the stomach were three mackerel, in different stages of digestion. 

 On removing the tongue and pharynx, with the larynx and trachea, 

 I perceived a nematoid worm grasped by the rima glottidis, one half 

 of it being within the posterior buccal orifice, and the other half 

 within the larynx. I am sorry to say it was afterwards lost, through 

 the carelessness of an attendant. The worm was about four inches 

 in length, much thicker than those in the heart, and of a dusky 

 hue. The thoracic viscera were removed en masse, when the lungs 

 were found studded throughout with miliary tubercle. The worms 

 were chiefly in the right ventricle of the heart, entwined and laced 

 amongst the columnee carnece, being embedded and surrounded by 

 blood-clot. The left side of the heart was quite free from worms ; 

 and there were none in the pulmonary artery or other large vessels. 

 When fresh the worms were extremely elastic, so that they might be 

 stretched to half their length beyond the natural size and yet would 

 not break. The muscular system generally was healthy. I have 

 sent you all the worms except two, which I preserved, and after- 

 wards gave to a friend." 



In offering this abstract of Mr. Coughtrey's lengthened and inter- 

 esting account of his examination, I have purposely selected only 

 sucli remarks as seemed to bear more or less upon the question of 

 parasitism ; and in doing so I have adhered very closely to the actual
