MONTAGU A GOXJLDII Verrill, sp. nov. 



Body elongated, nithVr slender; foot with tin-, anterior angles onl 

 slightly prominent, and obtusely rounded; posteriorly it tapers gnidu- 

 ally to an elongated slender point. Tentacles long, slender, not sornit.-. 

 the dorsal ones a little longer tban the oral; eyes small, hlack ; branrhml 

 papilla} fusiform, moderately stout, grouped in eight or more tran\ 

 rows 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 brin^ 

 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 papilla- 

 dark brown or reddish brown internally, with a ring of opaque white 

 close to the tips. 



Length about 20 mm . 



Off Thimble Island, in 4 to 5 fathoms, with the preceding species. 



This is nearly allied to If. Nananensis Stirnpson, 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 M. diversa (JEolis diversa Couth.), and one of his figures (Plate 

 19, fig. 280) 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. 2G7, 2G8_ 

 copied from Couthouy.)
