(7) TARPAULIN COVE. 



Tarpaulin Cove proved interesting in several respects. The westerly side (station 

 17) has a bottom of sand and gravel in 2% to 4 fathoms, and there was an abundance 

 of Desmarestia viridis and Antithamnion cruciatum, and in small quantities Cladophora 

 gracilis, Agardhiella tenera, Antithamnion plumula, Callithamnion Baileyi, and Grin- 

 nellia americana; the dredge brought up large quantities of Zostera. The upper end 

 of the cove (station 18) in 2}^ fathoms has a bottom of mud and gravel supporting 

 extensive beds of Zostera, and an abundance of Polysiphonia nigrescens. A line dredged 

 across the entrance of the cove (station 19) showed a muddy bottom with occasional 

 plants of Polysiphonia nigrescens. Hauls made at the entrance nearest the lighthouse, 

 July 18, 1903 (Phalarope), showed the presence of much Seirospora Griffithsiana and 

 small quantities of Desmarestia -viridis, Laminaria Agardhii, Agardhiella tenera, Calli- 

 thamnion Baileyi, Ceramium fastigiatum, Ceramium rubrum, Champia parvula, and 

 Grinnellia americana. 



(8) VINEYARD HAVEN. 



Station 69 off West Chop, at the entrance to Vineyard Haven, was very rich in 

 algae and especially interesting as a locality for Rhadinocladia Farlomii. The bottom 

 was sand and stones in 3^2 to 7 fathoms and supported extensive growths of Zostera. 

 There was much of the following : 



Hildenbrandia prototypiis. 

 Lomentaria uncinata. 

 Melobesia farinosa. 

 Melobesia LejoHsii. 

 Phyllophora Brodisci. 

 Phyllophora membranifolia. 

 Spermotliamnion Tumeri. 



Callithamnion coryrabosum. 

 Dasya elegans. 



Lithothamnion polymorphum. 

 Polyides rotundus. 

 Spyridia filamentosa. 



Ralfsia clavata. 



Rhadinocladia Farlowii (on Zostera). 



Sphacelaria radicans. 



Agardhiella tenera. 



Antithamnion cruciatum. ^ 



Callithamnion roseum. 



Ceramium tenuissimum. 



In small quantities were: 



Cladostephus vertillatus. 

 Desmotrichum undulatum. 

 Ectocarpus confervoides. 

 Sphacelaria cirrhosa. 

 Ahnfeldtia plicata. 



Vineyard Haven proper (stations 70, 71, 72, and 7762) presented little variety in its 

 algal life but considerable quantities of certain species. Station 70 in 4 fathoms, with a 

 bottom of stones and Crepidula shells, gave much Agardhiella tenera, Champia patiiula, 

 Grinnellia americana, and Lomentaria uncinata; in small quantities were Rhadinocladia 

 Farlowii (on Zostera), Antithamnion cruciatum, Callithamnion corymbosum, Ceramium 

 strictum, Ceramium tenuissimum, Hildenbrandia. prototypiis, Lithothamnion polymor- 

 phum, and Melobesia LejoHsii. Station 71, with a bottom of clam and pecten shells, 

 stones, and mud, in t,% fathoms, gave an abundance of Sphacelaria radicans, Agardh- 

 iella tenera, Champia parvula, Grinnellia americana, Lomentaria uncinata, and Phyllo- 

 phora Brodiwi. Station 72, stones and mud, in 3 to 4 fathoms, showed large quantities 

 of Calothrix confervicola, Sphacelaria cirrhosa, Agardhiella tenera, Champia parvula, 

 Lomentaria uncinata, Melobesia LejoHsii, and Spermothamnion Tumeri, and a few plants
