A. E. 'Verrill — Ttinicata and MoUuscoiclea of the J3ermudas. 591 



The gonads, which are found on both sides (fig. 8, g; g), consist 

 of about four double clusters of folicles arrani^ed alono- each side 

 of a curved tubular organ (d) attached to the tunic. 



Length up to 30'"'° ; breadth, 20-25""". 



Shallow water, on the reefs and under stones. 



Resembles If. rubrilahia externally, but can usually be distin- 

 guished by the redness of the entire test. 



Polycarpa multiphiala, sp. nov. 



Test brown, thick, leathery, tough, roughly wrinkled in contrac- 

 tion, ovate, depressed, attached by most of one side, partly covered 

 with adherent shell-sand ; apertures near together, on large, short, 

 thick, rudely wrinkled verrucre. Tunic smooth, soft, rather thick, 

 dark brown and nearly opaque, as preserved in formalin ; its mus- 

 cular bands are fine and numerous, the net-work rather irregular. 

 Siphons short and stout, enlarged distally; apertures with four large 

 lobes. 



Tentacles many, simple, slender, subequal, curved inward, pig- 

 mented on inside; 40 were counted in the type. Branchial sac has 

 4 broad plications on each side; 6-12 stigmata to a mesh (usually 

 8 or 9). Gonads attached to tunic, numerous, small, flask-shaped 

 with two small apertures at the free end. Intestinal bend small, 

 simple ; stomach enlarged. 



Length, 45'"™ ; breadth, 30""". 



On the reefs, not common. 



Allied to P. Mayeri Traust., of the Gulf of Naples. 



Diazona picta, sp. nov. 



Plate LXX. Figure 8. 



Forms large gelatinous colonies, consisting of a massive main 

 stem from which arise more or less numerous lobes, each lobe often 

 containing 12 to 20 zooids, which, in expansion, are much exsert 

 above the common mass, the free portion being slender and three or 

 four times as high as broad. Apertures, when expanded, on short 

 terminal tubes, the oral one larger and higher than the atrial. 



General color usually translucent pinkish white ; oral aperture sur- 

 rounded by a band of briglit carmine-red, edged on both sides with 

 flake-white ; a stripe of the same carmine color extends from the 

 oral band down the ventral side of each zooid.
