504 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.38. 



While they differ in some rainoi details, they arc specifically iden- 

 tical with specimens in the l". S. National Museum from Greenland, 

 and also with specimens collected by Mr. L. M. Turner in the Dngava 

 Bay region. 



Storer's brief description of Salmo immaculatus i- explicit enough 

 to indicate that it is this same species and not the sea-rnn brook trout 

 v fontinalis). For the purpose of comparison the Boston Society of 

 Natural History very kindly loaned the writer specimens of Salmon i da ■ 

 collected in Greenland by the Williams College Expedition in I860, 

 and in Labrador by Prof. A. S. Packard in 1864. Unfortunately, the 

 type of Salmo immaculatus could not be found; but the specimens 

 received supported t he ident ilication. Regarding some of them Pack- 

 ard wrote:" 



Salmo immaculatus II. 1!. Storer. Three specimens from near Hopedale were col- 

 lectedJuly 29th. These specimens are unquestionably referable to the n. immaculatus 

 of Storer and are distinct from the S. trutta of Europe, with which species Perley and 

 others have confounded them. They differ from S. trutta by having larger scales and 

 being without spots, as their name indicates (Putnam). 



Putnam was undoubtedly familiar with the type of S. immaculatus. 

 In the Packard collection were also two specimens concerning 

 which he wrote:" 



Salmo sp.? Two specimens from the Island of Ponds, near Domino Harbor, col- 

 lected in July. This species, which, from its rather iinperl'eei condition. I have not 

 been able to recognize, appears to be closely allied to the - s '. trutta of Europe, being 

 spotted as in that species, hut of somewhat differenl shape, especially about the head. 

 There are also specimens from ( Greenland belonging to this species in the collection of 

 this society, collected by the Williams College Expedition to Greenland and Labrador 

 in L860. 



These specimens were undoubtedly correctly identified with the 

 Greenland specimens with which the present writer compared them, 

 but Putnam was mistaken regarding the spots. Salmo trutta has dark 

 spots, and the spots of this form are light, pink or red. However, no 

 spots are visible at this time on the specimens under discussion. It is 

 not stated whether these specimens were taken in the sea, brackish or 

 fresh water, but one of them to a greater extent than the other resem- 

 bles it trout of the S. aljrinus group from fresh water. There are cer- 

 tain differences in measurements between these and the Greenland 

 specimens mentioned, but apparently they can mostly be accounted 

 I'm- by the differences in the sizes of the individuals. 



In the description of Salmo immaculatus Storer gave the diagnostic 

 points of difference between that specie- mid S. fontinalis, and, 

 although they have been ignored, there are good and strong specific 

 differences. These are: " Preopercle larger than in S. fontinalis," 



"scales larger than those of *S'. fontinalis," "caudal deeply forked."
