braue ; arms eight, of which six arc subtriangular, 

 the two superior ones a little shorter than the second 

 pair, which are equal to the inferior pair, third pair 

 very strong, rounded, and depressed, longer than the 

 others, furnished with a membrane at their exterior 

 part ; all the arms furnished with two series of suck- 

 ers, which are hemispherical, alternate and peduncu- 

 lated ; the disks are obliquely truncated, most ele- 

 vated on the exterior side, beneath indented for the 

 attachment of the conic peduncle, they are armed 

 with six horny brown teeth above, of which two su- 

 perior ones are narrow and pointed, and the four 

 others broader ; iuferiorly and upon the narrow side 

 of the disk is a long, horny, brown lamina ; the two 

 long arms, are subcylindric, dilated at their extre- 

 mity, margined on each side by an undulated mem- 

 brane, upon which the peduncles of , the suckers re- 

 pose ; four series of suckers, of which the middle 

 series are largest, and terminated at each extremity 

 by smaller suckers ; disks hemispheric, transversely 

 truncated, armed with a corneous circle, and having 

 strong remote teeth, with two or three smaller inter- 

 vening ones, in the central disks ; but I have not 

 been able to determine the number of intermediate 

 teeth in the lateral disks ; besides the thin lateral 

 membrane, i lere is another thicker one, placed ob- 

 liquely upon the enlarged extremity of the long 

 arms ; the opening of the mouth, has three concen- 

 tric folds, the exterior one of which is furnished 

 with a much folded membrane, which is terminated
