INVERTEBRATE ANIMALS OF VINEYARD SOUND, ETC. 66 T 



MoNTAGrUA Gottldii Verrill, sp. UOV. 



Body elongated, rather slender ; foot with the anterior angles only 

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

 ally to an elongated slender point. Tentacles long, slender, not serrate,, 

 the dorsal ones a little longer than the oral ; eyes small, black ; branchial 

 papillae fusiform, moderately stout, grouped in eight or more tranverse 

 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 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 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 M. 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 M. diversa (JEotis 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, 268,.
