and without grinding surface. Color brownish, without conspicuous 

 spots; sides and lower part of head silvery. 



This species is described from three specimens, each about 2i inches 

 in length, from the Upper Missouri region, collected by Dr. F. V. Hay- 

 den. This species is allied to H. hyostornus Gilbert, and H. cvstivalis 

 Girard. The former has a more projecting snout, the latter a smaller 

 eye, and both are profusely speckled with black dots. 



CONTRIBUTIONS TO THE HISTORY OP THE COMMANDER ISLANDS. 



No. 4. 

 A. Notes upon the plants collected on the commander islands (berino 



AND COPPER ISLANDS) BY LEONHARD STEJNEGER. 

 By ASA ORAV. 



The collection of phanerogamous plants, although not numerous in 

 species, is full of interest. 



The Ranunculacece are Anemone Richardsoni, A. narcissifiora, Ran- 

 unculus EschscholtzH, R. auricomus (which, at least, in the var. cassuHcuSy 

 has been found in Kamtschatka), and a form probably of 7?. repenSy 

 Caltha palustris, Coptis trifoUa, and Delphinium elatum. 



The CrucifercE are of small interest, a dwarf Nasturtium palustrCy 

 Barharea vulgaris, Arahis Oerardi, var. borealis of Kegel, Cardamine 

 hirsuta and C. pratensis, Draba incana, and a small species which may 

 be D. alpina. Viola mirabilis var. Langsdorffii of Kegel, and Y. biflora 

 of Kegel are all of tbat order. 



Of CaryophyllacecE there are Silene acaulis, Lychnis apetala, Arenaria 

 peploides, A. lateriflora, and A. macrocarpa, the remarkable Stellaria 

 radians, and the anomalous form of S. humi/usa, called var. oblongifolia 

 by Ledebour, with long and lax stems, elongated internodes, and a habit 

 quite unlike the ordinary form of the species ; also the forms of Ceras- 

 tium alpinum, which are common in that region. 



Claytonia sibirica and G. arctica represent the Portulacece, and Gera- 

 nium erianthum represents its order. 



It is rat<her remarkable that there is only one leguminous plant in the 

 collection, namely, the widespread Lathyrus maritimus. 



The Rosacece are Spirceakamtschatica, Geum calthifolium, Xx. Rossii,and 

 a dwarf G. macrophyllum, JSrbhaldia procumbens, Fotentilla fragiformis, 

 var. villosa of Kegel and Tiling, and the ubiquitous P. Anserina antl P. 

 palustris, Rubus stellatus, aud R. Chamccmorus, and a small-leaved Pj//'ws 

 sambucifoUa. 



Saxifrage are rather numerous: A dwarf >S'. Hirculus, and a still 

 smaller one, which seems to be 8. chrysantha, Gray; S. bronchialis, S. 

 unalaschensis of Sternberg (which is 8. flabelUfolia and near to S. Da- 

 hurica, which we seem not to possess, the North American plant, so called,
