Besides by ihe presence of olochideal dorsal bristles, characterised by their toothed 

 (not fringed) ventral setae.

The laroest specimen has a length of 20 mm.; its breadth (without bristles) is 9 mm., 

 whereas the number of segment amounts to 32. 



The body has an oblong-ellipsoidal shape, with the broadest segments in the median 

 area, whereas in H. hvstrix the segments over a large part of the body have the same breadth. 

 All bristles are yellow, only the glochideal setae are darker coloured at their base and distal 

 extremity; they are directed towards the median dorsal line, whereas in H. hysirix and H. 

 malleata these setae are conspicuously brown-coloured and flanking the lateral sides of the 

 body. The glochideal brisdes (PI. XII, figs. 7 and 8) have a long, pointed spear-head and 

 two reciu-ved fangs at one side and three at the opposite, the inferior of them being the 

 largest, about twice as long as the superior ones; the distal part of their shaft is smooth, the 

 inferior part covered with small tubercles. The short dorsal bristles (PI. XII, fig. 9) of the elytral 

 segments are slightly curved, covered with minute tubercles and provided with a smooth, trans- 

 lucent tip; they are quite differing from those in H. hysirix. The tip usually is surrounded by a 

 caj) of fine threads, that appear to emerge from it. The bifurcated ventral setae are provided with 

 a small accessory tooth above the large spur (PI. XII, fig. 10). The head is rounded, nearly 

 as long as broad, with two large oval eye-peduncles on its frontal margin, each provided with 

 a large black spot; between them a short tentacle arises, consisting of a conical, tuberculate 

 basal part, a median joint nearly twice as long as the preceding and a short, clavate distal 

 part (PI. XII, fig. 6). The palps are rather long, tapering distally. The tentacular cirri are 

 slender, not quite as long as the palps, like the other cirri provided with a clavate terminal 

 joint; the ventral cirrus measures two thirds of the dorsal one.

At Station 310 a Hermione was caught, long about 20 mm., that presumably belongs 

 to //. malleata Gr.. It much resembles H. hystrix, not only in its external appearance, but 

 also in the presence of .stout, dark-b.rown glochideal setae, that are directed somewhat ontward
