Pearl Islands, brought from 6 to 8 fathoms below low-water mark 

 by divers, — F. H. Bradley. 



Var. miser, 



Corallum dwarfed, forming small, thickly branched, rounded, c:es- 

 pitose clumps, from two or six inches in diameter and about the same 

 in height, the subdivision taking place rapidly from close to the base. 

 Branches and branchlets small and slender, the latter a little enlarged 

 toward the ends, and from •o to 2 inches long. Verrucie as in the typ- 

 ical form, but smaller, nearly obsolete on the larger branches. Colorof 

 branchlets deep brown, of branches and often tlie bases of brancMets 

 very light yellow. Diameter of branchlets *10 to •IS; length of long- 

 est verruc;e ^04 to •OG of an inch. The spieula are similar to those of 

 the typical form, but smaller. 



Pearl Islands, in rocky pools at extreme low- water mark, — F. H. 

 Bradley ; Corinto,— J. A. McNiel. 



This species is more nearly allied to M. echiiuita than to any other. 

 Its cffispitose growth and far more numerous and smaller branches 

 will usually separate it readily. The verrucas are smaller and 

 shorter, and the spieula are different, though quite similar iu general 

 appearance. They are mostly stouter and blunter than the corres- 

 ponding forms in 31. echinata^ while the large, stout spindles of the 

 coenenchyma are decidedly larger, even in smaller specimens. The 

 medium sized spindles are also decidedly stouter and less acute. 



Muricea anstera Verriii, sp. nov. 



Plate VIII, figure 7. 



Corallum large, dichotomous, fruticose, sometimes ca'spitose, with 

 rather thick, obtuse branchlets, covered with close, scarcely ajipressed, 

 sub-conical verrucae, having an acute lower lip. 



In the largest specimen, several trunks arise from a broad base, four 

 or five inches in diameter. These quickly fork, and the branches in their 

 turn rapidly divide, being, in some cases, five or six times dichotomous, 

 producing a rather coarse caespitose clump, though some of the m:,iu 

 branches and their di^•isions have a tendency to arrange themselves in
