With Plate 24-25. 
During a recent trip to the Barbados Island I examined a 
small collection of alcyonarian corals that had been secured from 
a cable ship operating to the “northwest of the Florida coast”. Among 
these was a solitary specimen of solenogastre taken at a “depth of 
over a mile”. From the position of the animal it is not possible to 
decide whether it was originally attached to what is evidently a 
species of Acanthogorgia, or whether its lodgement in a mass of 
sponge and stony coral encrusting the base is accidental. 
The animal measures 23 mm in length by 1,5 mm behind the 
head region where the diameter is greatest. From this point 
posteriorly the body gradually diminishes in size until the cloacal 
chamber is reached where the coelomoducts, their appendages and 
muscles produce a slight enlargement. The form of the head region 
is represented in Pl. 25 Fig. 13. Under low magnification the body 
has a spongy, reticulate appearance, the papillae occupying a some- 
what sunken position corresponding to the meshes. The color in 
alcohol is light yellowish white. 
The, cuticle investing the body varies somewhat in height, but 
on the lateral and dorsal surfaces of the animal it measures approxi- 
mately 0,12 mm in thickness. After decaleification it presents a 
decidedly shrunken appearance; and the papillae and the hypodermis
