R. Pcalo. It appears to mc not rcfera^)lc to any of the species fig- 

 nred by Seba, nor of those published l)y Montfort. 



Tlie sac is solid, firm, cylindrical, gradually attenuated to a point, 

 and furnished with a fiat appendice anteriorly ; fin terminal, more 

 than half as long as the body, united in a point posteriorly, lateral 

 angles rounded, lateral and jwstcrior sides thickened, anterior side 

 thin, surface with transverse striae, formed by small muscles ; head 

 small, compressed, with a small transverse membrane each side be- 

 low the eyes ; neck small, short ; eyes covered by a membrane ; 

 arms eight, of which six are sub-triangular, 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 suckers, which are hemispherical, 

 alternate, and pedunculated ; the disks are obliquely truncated, 

 most elevated on the exterior side, beneath indented for the attach- 

 ment of the conic peduncle, they are armed with six horny brown 

 teeth above, of which two superior ones are narrow and pointed, 

 and the four others broader ; inferiorly and upon the narrow side 

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

 sub-cylindric, dilated at their extremity, margined on each side by 

 an undulated membrane, upon which the peduncles of the suckers 

 repose ; four series of suckers, of which the middle series are largest, 

 and terminated at each extremity by smaller suckers ; disks hemi- 

 spheric, transversely truncated, armed with a corneous circle, and 

 having strong remote teeth, with two or three smaller intervening 

 ones in the central disks ; but I have not been aide to determine 

 the number of intermediate teeth in the lateral disks ; Ijesides the 

 thin lateral membrane there is another thicker one, placed obliquely 

 upon the enlarged extremity of the long arms ; the opening of the 

 mouth has three concentric folds, the exterior one of which is fur- 

 nished with a much folded meml)rane, which is terminated by six 

 small appendices, or false arms, furnished with several suckers at 

 their extremities, the two inferior appendices shorter. 



The bone is broad, naviculiform, terminated in a point at each 

 extremity, thin at the margin, carinated, and a little more robust 

 at the anterior extremity, which is narrowest. 



The superior part of the head, of the tentacula, and of the back 

 covered with reddish-brown points, which are less numerous upon 

 the sides and aljdomen.
