den and Paris, and o{ Mot.flava, the otive-headed JVagtail, of England, 

 all killed in the month of May. 



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

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



Mr. Gould also stated, that he had recently see-n a fine specimen » 

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

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

 rarely been ,kno\vu to range weslward of the European continent, 

 had been only once previously observed in England. 



Mr. Owen referred to bis Notės (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 vvhich, the 

 Das. 6-cinclus, 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 šame sex, having subseąuently 

 come under bis examination, he \vas enabled to confirm some of the 

 peculiarities observed in the dissection of the young malė 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 tlie U'easel-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 (\vhich died before the young one had 

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

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

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

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

 conglomerate mammary gland vvas found, extending across the vvhole 

 sternal aspect of the thorar, 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 vvas of a deep yello\v 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 vvith mercury, I was 

 unable to force any into the opposite side. 



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

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

 resembling more the corresponding organ in the malė : it vvas of a 

 pointed form, vvas covered vvith a leaden-coloured integument, and 

 vvas situated an inch anterior to the anus į the genito-urinary orifice 

 vvas 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 foro 

 lines further vvithout any diminution of diameter, and terminating in 

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

 small orifice, In Das. Peba, the genito-urinary cavity vvas not sepa- 

 rated by a corresponding contraction from the urinary bladder, but 

 was a more direct continuation of it j so tiiat in both these species \ve
