Horizon and Locality. Type from lowest beds of shaly 
limestones in Alexandra Falls section. Hay river, below 
Alexandra falls 9 miles (just above first island below the falls). 
Collector, E. J. Whittaker. A second "nearly perfect specimen 
was found by Mr. Lowe, geologist of the Imperial Oil Company : 
and presented to the Canadian Geological Survey. 
No. 5658, from an horizon about 200 feet higher than the 
last, is of a larger and more robust type, with very low, flat 
plates. Unfortunately the only specimen lacks the basal plates 
and is only partly free from the matrix; but even with these 
meagre points for comparison it is clearly distinct, and should 
be given a name, for which is proposed — 
Melocrinus canadensis n. sp. 
Plate I, figure 3 
In the flatness of the plates this form is comparable with 
one from the Hamilton of western New York figured by Hall, 
but never described, under the name M. breviradiatus , as figures 
18, 19, of Plate I, of the photographic plates privately dis- 
tributed about 1872, as part of Bulletin 1, of the New York 
State Museum. 
Estimated dimensions of calyx: 28 mm. high by 26 mm. 
wide. 
Locality and Horizon. Near top of Devonian section. 
About i\ miles above Alexandra falls, Hay river, and ^ mile 
above second island above the falls. Collector, E. J. Whittaker,
