not carinate nor serrate; caudal peduncle moderate, its depth being con- 

 tained 1.5 times in its length. Head simiLar to C. viysficetus; the snout 

 longer, contained 5.5 to 7 times in head, 1^ times in eye ( the snout contained 

 8 to 9 times in head in C, myaticefiis). Both Jaws bear minute teeth, those 

 on the maxillary largest. Branchiostegal membranes united for only | to 

 f of the distance between tip of mandible and mandibular articulation, 

 wholly free from the isthmus. Tip of mandible directly beneath the 

 anterior boi-der of orbit. Gill rakers long, ,''„ diameter of eye, 20 to 30 on 

 the upper limb, 25 to 30 on the lower limb; in 5 examples as follows: 

 25 + 30, 27 + 25, 30 + 26, (23 + 29 to 20 + 25 ), 25 + 30. The origin of the 

 dorsal is midway between base of median caudal rays and a point varying 

 l)etween front and middle of the eye. Insertion of anal below the poste- 

 rior fourth or third of the dorsal, its length equaling the distance from 

 the posterior border of the eye to insertion of pectoral. The pectoral is 

 short, 2i to 2^ in head, failing to reach the insertion of the ventrals by i 

 or nearly i its length. Caudal deeply forked, its median rays 2^ to 3 times 

 in head. Color uniformly silvery with a distinct, well-defined lateral sil- 

 very band extending from upper angle of gill opening to base of caudal, 

 its greatest width equaling the diameter of orbit, becoming narrower on 

 caudal peduncle. This species differs from C. mi/sticctns in the much nar- 

 rower union of the gill membranes, the less numerous gill rakers, and 

 in the longer snout. Length 1^ to 2k inches. Panama Bay. Not rare.

 none of them is properly described as '' canine-like."

Page 465. Dr. G. A. Boulenger has kindly sent us the following note 

 regarding the types of Coregonus richardsonii which are in the British 

 Museum: 



I have examined tlio types (dry) of Coregonus richardsonii. There arc about 20 gill 

 rakers on the lower part of the anterior .arch, the longest A the diameter of the eye. The 

 maxillary extends to below anterior border of eye, and its length is 4 times in length of
