3. Cyanopica cooxi, Bp. Capite levi, supra tantum nigro- 
chalybeo : dorso cano-rubello, nucha albicante: rectricibus 
lateralibus late albo terminatis, mediis modice elongatis vix 
apice albis. 
Synonyms. 
Pica cyanea, Cook. 
Pie bleue d’ Europe, Schlegel (Cyanopica europeea). 
Cyanopolius Cooki, Bp. Brit. Assoc. Birmingh. 1849 ; Gould, Eur. 
t. 217; Susemihl, Eur. Vog. t. 
Hab. in Eur. mer. Hispania. 
We are thus arrived to the genus Pica, Br., or true Magpie (the 
pied long-tailed), which, as we observed from the beginning, must 
close the Garruline series, which it connects with the Corvide, show- 
ing as much affinity to those larger Crows as the first of the Jays do 
to the smaller Shrikes or Laniide. Of such Magpies we know eight 
species perfectly typical and quite close to each other, whilst two 
birds still allowed to remain in it are abnormal, each deserving of a 
genus by itself: to both these birds, however different in form and 
colour, the name of Corvus caledonicus has been applied, one of which 
is the slender-billed, more jay-like Pica albicollis, Vieill., Garrula 
torquata of the ‘ Pl. Col.’ of Temminck, to which the generic name of 
Streptocitta might be applied; whilst I propose that the name of 
Gazila (so congenial in this our family), applied to the legitimate 
Corvus caledonicus, should honour the person and perpetuate the 
martyrdom of a highly refined and scientific ecclesiastical friend of 
humanity, the lost victim of clerical machinations ! 
2. MonoGRAPH OF SPHZENIA, A GENUS OF LAMELLIBRANCHIATE 
Moxuvusca. By ArtHur Apams, R.N., F.L.S. etc. 
(Mollusca, Pl. X.) 
In the unrivalled Collection of Mr. Cuming is a group of Bivalve 
shells, which appear to be neither Mya nor Corbula, but partaking of 
the characters of each. The animal, which is also preserved in spi- 
rits, resembles that of Coréula in having short united siphons, a small 
compressed foot, and in the mantle being closed, with the exception 
of an anterior elliptic opening; the shells, however, have the hinge of 
Mya, but do not gape at both extremities. The only genus, there- 
fore, into which they resolve themselves is Sphenia of Turton, which, 
with the hinge of Mya, gapes only at one end, and which moreover 
is deprived of a long coriaceous siphon. Mr. Hanley has published 
one species in the ‘ Zoological Proceedings,’ under the name of Mya 
semistriata, and M. Deshayes another, under that of Corbula decus- 
sata, in the ‘ Magazin de Zoologie,’ 1844, and I had described a 
third, under the name of Spitenia Mindorensis, in the ‘ Zoology of 
the Voyage of H.M.S. Samarang ;’ and to these I now add several 
other large exotic species collected by Mr. Cuming.
