C. skua; C. lonnbergi lonnbergi is tlie New Zealand form ; 

 and two new subspecies — C. I. clarkei and C. I. interniedius — 

 are proposed for the South Orkney and Kerguelen birds. 

 The suggested subspecies of C. maccormicki (C. m. wilsoni) 

 from Weddell Sea seems premature, as it is founded on two 

 examples only. Coprotheres is used for the '* Poraatorhine 

 Skua'^ and Stercorarius for the "Arctic Skua/^ while a 

 new genus Atalolestris is made for " Buffon^s Skua.'' 



Vol. iii. begins with the Charadriiformes, wherein 

 Mr, Mathews states his preference for small groups^ in the 

 face of the difficulty of clearly limiting those that are larger. 

 His families are Morinellidre (Morinella = Strepsilas), 

 Haematopodidse, Charadriidse (Lapwings and Plovers only), 

 Recurvirostridee, Ibidorhynchidae, ScolopacidsCj and Phala- 

 ropidee. 



Pluvialis is used for the Golden Plover section ; Cliaradrius 

 for jSigialitis ; Cirrejndesmus for Charadrlus bicinctus and 

 C. monyolus', while two new genera are propounded, Pagoa for 

 Charadrlus geoffroyi and Eupodella for C. veredus. Moreover, 

 the author limits Lohlbyx ( = Loblvanellus) to the Australian 

 and Moluccan species, and proposes new genera — Afribyx 

 and Roglbyx — for the African and Malayan forms. Lobibyx 

 has two Australian species, one with three subspecies; 

 Hamatopus ostralegus has five subspecies (including longi- 

 rostris, but sinking H. I. mattlngleyl) ; H. niger has six 

 subspecies ; H. quoyi of tlie Falklands is granted a special 

 subgenus Prohamatopus ; Erythrogenys and Zonlfer have 

 two subspecies eacb. Clrrepidesmus airlfrons of Wagler is 

 shewn to be a subspecies of C. monyolus ; its synonymy is 

 discussed, and the author's C. bicinctus incertus is now sunk. 



The illustrations are of their usual excellence, and good 

 figures are given of several of the heads, bills and legs.
