Whale which had been presented by His Excellency Sir William 

 MacGregor, K.C.M.G., Governor of Newfoundland. The foetus 

 measured 190 mm. in length, measured along the curved dorsal 

 surface from tip of head to tip of tail. The specimen, which is 

 represented on Plate I., showed, among other interesting features, 

 a well-developed anal fin, the existence of which in whales had 

 recently* been called in question, although already indicated for 

 the young of this species in a figure by G. 0. Sars.f A series 

 of microscopic sections through one-half of the lower jaw 

 demonstrated the presence of a series of fourteen tooth germs. 

 Sections through the palate showed a uniform coating of 

 epithelium without any indications of approaching " whale-bone " 

 formation. 



2. Amongst other objects exhibited were specimens of remark- 

 able balls of hair from the uterus of a fur seal (probably Otaria 

 ursina), and pointing to the occurrence of a particularly well- 

 developed lanugo in this form. 



3. Pennella balaeiwpterae, Kor. and Dan. — There were ex- 

 hibited several specimens of this gigantic Copepod, which lives 

 as a parasite on whales. The specimens measured about 250 mm. 

 in lengths exclusive of the egg strings. They had also been 

 obtained by Sir William MacGregor, and had been " attached to 

 the host near the line of junction of the dark back with the 

 white belly, and projected about two inches by the narrow 

 end into the blubber; the parasites were numerous." Almost 

 synchronously with the arrival of these specimens there appeared 

 a memoir upon the structure of Pennella balaenopterae, by Sir 

 William Turner, based upon specimens from Shetland, and about 

 the same time, I am informed, specimens were obtained by the 

 Cambridge Museum of Zoology. In view of Sir William Turner's 

 full description, it does not seem necessary to describe the 

 specimens of Pennella. The specimens exhibited were all 

 females, the male, which is probably of relatively small size, 

 not having been observed.
