MontTacua GouLpi Verrill, sp. nov. 
Body elongated, rather slender; foot with the anterior angles only 
slightly prominent, and obtasely rounded; posteriorly it tapers grada- 
ally to an elongated slender point. Tentacles long, slender, not serrate. 
the dorsal ones a little longer than the oral; eyes smail, black : branchial 
papill fusiform, moderately stont, grouped in eight or more tranverse 
tows on each side, the rows being grouped two by two, so as to form 
transverse clusters. with two rows each, the rows of the clusters being 
separated by spaces narrower than those between the clusters. Color 
of body light yellow or tinged with pale orange: tentacles pale orange, 
with a flake-white stripe on the posterior surface; branchial papille 
dark brown or reddish brown internally, with a ring of opaque white 
close to the tips. 
Length about 20". 
Of Thimble Island, in £ to5 fathoms, with the preceding species. 
This ts nearly allied to 1. Mananensis Stimpson, but the angles of the 
foot are less produced and not acute, and the proportions of the tenta- 
cles are different. Dr. Gould seems to have confounded this species 
with MW. dirersa (Molis diversa Couth.), and one of his figures (Plate 
19, fig. 250) apparently represents this species; but certainly does not 
represent M. diversa, which was originally described and figured as hav- 
ing the oral tentacles longer than the dorsals (See Gould's figs. 267, 268, 
copied from Couthouy.)
