PLATE VIII. 
Epizoanthus Americanus on Eupagurus pubescens. Natural size. From the 
Gulf of Maine, 1873. 
Adamsia sociabilis V. on Catapagurus Sparreri A. M.-Edw. (= Hemipagurus 
socialis Smith), drawn from life. Side view in its natural position, en- 
larged 2 diameters, showing the basal chitinous pellicle from which the 
basal disk has partially withdrawn. In this example it had a fragment 
of Dentalium for a nucleus. 
Adamsia sociabilis V., without the crab. Another example, seen in a 
posterior view, drawn from a living specimen, showing the chitinous 
basal secretion, which enclosed the crab, and had been partially uncov- 
ered by the contraction of the basal disk. 
Urticina consors V. on Sympagurus pictus Smith. One half natural size. 
Drawn from the living specimens in natural positions. 
Epizoanthus paguriphilus V., on Parapagurus pilosimanus Smith. Natural 
size. Drawn from an alcoholic specimen partially contracted. 
Epizoanthus Americanus V., peculiar variety, on a tube of JZyalinecia arti- 
jez V. Natural size. 
Figures 2 to 5 are from specimens dredged off Martha’s Vineyard by the 
U. S. Fish Commission, in 1880 and 1881. For the use of these and 
several other drawings of actinians made from life, I am indebted to the 
U. S. Fish Commission. All the drawings were made by Mr. J. H. 
Emerton.
