pillosus and -S'. Harveii, the body being entirely without the di- 

 stinct distant paj)ilhe of tlie former species ; wliile on the otlier 

 handj instead of being smooth as in the S. Harveii, it is minutely 

 but regularly granulated, the granules being close together and 

 unifonnly distril)uted over the body, except at the posterior ex- 

 tremity and basal half of the trunk, where the sui-face is rendered 

 rugged by larger tubercles and deep transverse irregular rugse. 

 Colour usually a uniform dull brown. Length about 7 inches ; 

 diameter of body about 9 lines. A ery common at lloundstone 

 bay in certain localities. 



Syrinx Furbesii (M^Coy), PI. XVI. fig. S.—Sjj. Ch. Posterior 

 half of the body suddenly attenuated; extremity dilated, club- 

 shaped ; trunk slender, dilated towards the extremity, granulated 

 its entire length to the base of the tentacula, remainder of the 

 body perfectly smooth. 



The form and proportions of this species arc nearly those of 

 the »S. nudus, from which it is distinguished by its smaller size, 

 perfectly smooth body, and in having the proboscis granulated to 

 the base of the tentacula. The extremity of the trunk is conical, 

 narrow, surrounded by a circle of short digitate tentacula, behind 

 which the trunk is rather inflated for a short distance and marked 

 with minute granules disposed in circular lines ; the remainder of 

 the proboscis, forming about one-fovu-th of the entire length of 

 the animal) is of a considerably smaller diameter and covered 

 \nth a minute crowded granulation ; with the exception of the 

 trunk, the entire animal is perfectly smooth : where the gi'anular 

 portion ceases the body is abruptly dilated to nearly four times 

 the diameter of the trunk, and continues cylindrical for about the 

 same length, when it again diminishes to about one-third its dia- 

 meter, and so continues to the posterior extremity, which is di- 

 lated into a pear-shaped knob. The anal pore is situated on the 

 dilated smooth portion of the body, a little below its junction 

 with the trunk. 



Not micommon at Roundstone bay, Connemara, from whence 

 there are specimens in the museum of the Royal Dublin So- 

 ciety. 



Syrinx tenuicinctus (M'^Coy), PI. XIV. fig. 4. — Sp. Ch. Cylin- 

 drical, diameter of body from the base of the trunk to the poste- 

 rior extremity perfectly uniform ; posterior extremity obtuse, 

 slightly mucronate at the tip; tnmk about one-seventh of the 

 entire length ; tip obtuse, surrounded by a few rows of minute 

 puncta ; entire sui-face of the animal sharply striated concentri- 

 cally : with a lens the trunk and a small portion of the posterior 

 extremity are seen to be also marked with numerous faint, short, 

 rather distant, longitudinal striae. 



It is only after much hesitation that I have ventured to cha-
