den and Paris, and of Mot.flava, the olive-headed Wagtail, of England, 

 all killed in the month of May. 



He added, that he regarded the Mot. cinerea of Ray as the young 

 or female of the grey Wagtail, Mot. boarula, Linn. 



Mr. Gould also stated, that he had recently seen a fine specimen 

 of Cypselus alpinus, 111., which had been shot by the gardener of Mr. 

 Holford, at Kingsgate, near Margate. This fine Swift, which has 

 rarely been | known to range westward of the European continent, 

 had been only once previously observed in England. 



Mr. Owen referred to his Notes (published in the First Part of the 

 'Proceedings,' pp. 141 and 154) on the anatomy of individuals of 

 two subgenera of the Linnaean genus Dasypus ; one of which, the 

 Das. 6-cinctus, Linn., had not, he believed, been previously dissected. 

 He stated, that two other individuals of that species, one an adult 

 female, the other a young one of the same sex, having subsequently 

 come under his examination, he was enabled to confirm some of the 

 peculiarities observed in the dissection of the young male specimen, 

 and particularly the existence of the double cacum, and the additional 

 lobe of the lungs. He was also enabled to add to that account a de- 

 scription of the genital and mammary organs. 



" The number of nipples in the Weasel-headed Armadillo (Das. 6- 

 cinctus) is two only, while the nine-banded Armadillo (Das. Peba, 

 Desm.) has four (see Part I. p. 1 42). They are situated in the pectoral 

 region, and in the adult female (which died before the young one had 

 ceased to suck,) were elongated to the extent of an inch and a half 5 

 at the apex of each were six minute orifices of the tubuli lactiferi; the 

 nipples were very soft and silky to the touch, and extremely flexible. 

 On removing the integument from this region, one large mass of 

 conglomerate mammary gland was found, extending across the whole 

 sternal aspect of the thorax, from one axilla to the other, and mea- 

 suring in length 5 inches, the thickness of the mass being from 3 

 to 4 lines : it was of a deep yellow colour. There was not the 

 slightest trace of a division at the mesial line ; but although I suc- 

 ceeded in injecting one side of this large gland with mercury, I was 

 unable to force any into the opposite side. 



"The clitoris in this animal was much longer than in the nine- 

 banded species, measuring 9 lines in the undisturbed state, and 

 resembling more the corresponding organ in the male : it was of a 

 pointed form, was covered with a leaden-coloured integument, and 

 was situated an inch anterior to the anus; the genito-urinary orifice 

 was placed on an eminence half an inch from the extremity. From 

 this orifice the genito-urinary canal extended 8 lines, receiving the 

 vagina by a transverse semilunar slit, and being then continued for 5 

 lines further without any diminution of diameter, and terminating in 

 the form of a cul de sac, into which the urethra opened by a very 

 small orifice. In Das. Peba, the genitourinary cavity was not sepa- 

 rated by a corresponding contraction from the urinary bladder, but 

 was a more direct continuation of it 5 so that in both these species we
