of preservation. It has a total length of about 23 inches or 5.94 cm. The 
exact date of its capture is not recorded, but it was taken “A few weeks”’ before 
Mr. Jones read his paper in November, so that it was evidently spawned the 
same year and is only a few months old. The second Halifax specimen has an 
extreme length of 7.6 centimeters or about three inches (Fig. 2). It weighs 
5.2 grams or about 5 of an ounce. There is likewise no exact date of capture 
recorded for this specimen, but like the last it was obviously spawned the same 
year. The largest of the three young specimens caught in Halifax Harbour, and 
at present in the Provincial Museum, measures 13.3 centimeters or about 514 
inches. It weighs 3414 grams or 13 ounces. This specimen belongs at least 
to the previous year. 
A specimen of the Angler caught on August 12th, 1910, at Campobello 
Island, Bay of Fundy, and preserved in formalin, had an extreme length, measured 
from the tip of the lower jaw to the extremity of the tail, of 11.2 centimeters or 
about 41% inches and weighed 15.7 grams or about half an ounce (Fig. 3).

Though slightly shorter than the Halifax specimen there is a considerable 
difference in development. The pectoral fins are membranous, wing-like struc- 
tures and comparatively wide, being 3 centimeters or about 1 3/16 inches when 
expanded, while in the latter specimen the pectorals have become thick, flipper- 
like structures apparently more adapted for crawling than swimming. The 
ventral fins of the Campobello specimen are long and narrow, and lie parallel 
to the long axis of the body, while in the Halifax specimen they are broader 
with strongly developed rays. They are now directed backwards and outwards, 
crossing over the axils of the pectorals. The head in both specimens is about 
one-third the length of the body. The Campobello specimen also belongs at 
least to the previous year. 
OTOLITHS AND THE RATE OF GROWTH. 
In determining the age and growth of fishes the scale method has been 
employed in recent years with much success. As the Angler is without scales
