the white-necked raven sometimes ascends to considerable hei 
and sails in slow, wide circles somewhat like the Dusen a 
considerable distance eastward over the plains. I have seen it at 
least a hundred miles east of Denver. I venture to suggest that 
its range will be found to join that of C. Americanus on the east, ; 
and that of C. corax on the north, being thus the southwestern 
representative of the genus. —T. Martin Tripre, Denver, Col. 
RELATION OF THE C@LENTERATES AND EcrrNoperms.—At the 
close of an important paper entitled “ Studies on the Devel 
of the Meduse and Siphonophora” in a late number of Siebold 
and Keelliker’s Zeitschrift Metschnikoff, a Russian zoologist, tH 
expresses his views as to the affinities of the Ceelenterates and 
Echinoderms drawn from a study of the larvae of the two 
“In conclusion I will again affirm that I regard the Ceelente | 
and Echinoderms as two different types, but which have so] 
relatives on both sides, that they should always be placed next 
each other in the system. I think that between the two there 
the same grade of similarity as between the higher worms (q i 
dinea, Gephyrea and Annelides) and the Arthropods (Insects a 
Crustacea). In order to be assured of this, we must obse.: 
bearings of embryological facts, and in regard to the Ceelentel 4 
and Echinoderms not forgot, that the body-cavity and peri 
cavity represent two different things.” This is opposed e 
view which Huxley and some German naturalists entertain 
the affinities of the Echinoderms, placing them next 
and breaking up the type of radiates (which view is f 
just at present in Europe ;) and confirmatory of the view 
who adhere to the Cuvierian type of Radiates.
