PLATE XI. 



Fig. 1. Canobius modulus (Dawson), restored outline with the striation and serration of 

 the scales left out; twice the natural size. Page 31. 



Fig. 2. Canobius modulus, type specimen, twice the natural size, from a photograph. In 

 this specimen, obtained by Frank D. Adams, at Beliveau, N.B., the orbit is con- 

 spicuous, the tail is very distinct, and the scale ornamentation throughout well 

 shown, but the dorsal ridge' scales are not in view. Twice the natural size. 



Fig. 3. Canobius modulus, a specimen from Horton, N.S., showing the number and shape 

 of the dorsal ridge scales; from a photograph. Twice the natural size. 



Fig. 4. Canobius modulus, anterior flank scales, from the two rows beneath the lateral line 

 scales, in the type specimen from Beliveau, N.B.; twelve times the natural size. 



Fig. 5. Canobius modulus, anterior dorsal scales, next to the enlarged ones of the dorsal 

 ridge, from the type; twelve times the natural size. 



Fig. 6. Canobius modulus, posterior flank scales, beneath those of the lateral line, in the 

 type specimen; enlarged twelve times. 



Fig. 7. Canobius modulus, dorsal ridge scales, about half-way between the head and the 

 dorsal fin, in the specimen from Horton, N.S. Similarly enlarged.
