Ci.)g;mi^ brhjichi, Yarrell i. 



Sj'ii. Cygnus minor, Auct. 



Smaller than the preceding, the length of the tarso-metatarsus 

 not exceeding 0,110. Both in this species and C. immutahilis the 

 groove on the njiper part of the anterior face of this bone is shallow, 

 and the bar below the foramen between the second and third 

 trochlea3 is very short. 



Hah. Europe. 



A 73 a. A right tarso-metatarsus, not improbably referable to a 

 female of this species ; from peat at Newport, Monmouth- 

 shire. The length of this bone is 0,092. 



Presented hy J. E. Lee, Esq., 1885. 



Cygnus falconeri, Parker 2. 



Syn. Cygnus melitensis, Falconer ^ (MS.). 



Typically about one third larger than C, olor, the length of the 

 tarso-metatarsus being 0,134 ; and characterized by the relatively 

 shorter femur, longer tarso-metatarsus, and the extreme shortness 

 of the phalangeals of the pes. In these respects the species approxi- 

 mates to Anser. 



The type specimens are described and figured by Parker in the 

 « Trans. Zool. Soc' vol. vi. pp. 119-124, pi. xxx. (1869), most of 

 them belonging to females. 



Hob. Malta. 



The folloiving specimens were obtained from the Pleistocene deposits of 

 Zebbug Cave, and were presented by Admiral Spratt, C.B., 

 1878 ; tJiey mostly indicate females. 



49323. The imperfect distal portion of the right tibio-tarsus. This 

 (Fiy.) specimen (fig. 27) has a transverse diameter of 0,028, 



against 0,02G in C. musicus ; it agrees in size with the 

 ty-pe tibio-tarsus figured by Parker in the memoir cited, 

 and probably belonged to a female. 



49324. A more imperfect specimen of the distal portion of the 



right tibio-tarsus. 



49322 a. Fragment of the distal extremity of the left tibio-tarsus.
