HERMAPHRODITE. 229 



Mandibles, with five or six teeth, with the second, (or 

 second and third, when there are six teeth,) smaller than 

 the others ; in two specimens, there were five teeth on one 

 side and six on the other; inferior angle rather broad 

 and strongly pectinated. 



Maxilla with the edge nearly straight, without any 

 notch, but with the inferior portion very slightly pro- 

 jecting; there are twelve or thirteen pairs of unequal 

 spines, of which some of the middle ones are rather 

 longer than the others, and almost as long as the two 

 upper great spines. 



Outer Maxilla. — On the inner margin the bristles are 

 divided into two separate tufts ; exteriorly, near the base, 

 there is a distinct rounded swelling with bristles. The 

 olfactory orifices are highly protuberant, approximate, 

 flattened, scarcely tapering towards their upper ends. 



Cirri. — The five posterior pair are elongated, very 

 little curled, with short pedicels ; their segments are 

 long, not at all protuberant in front, bearing five or six 

 pairs of long, slightly serrated spines, with a very minute 

 tuft of bristles between each pair, and with some short 

 lateral spines on the inner side of each segment ; on the 

 fourth pair of cirri, these lateral spines are considerably 

 developed; dorsal tufts consist of fine spines, with one 

 much longer than the others. First pair short, separated 

 by a wide interval from the second; rami unequal in 

 length, by between two and four segments ; longer 

 ramus having nine segments, scarcely half as long as the 

 rami of the second cirrus ; shorter ramus with seven 

 segments ; in the same individual there were twenty 

 segments in the sixth cirrus. The segments in the 

 shorter ramus of the first cirrus are oblong in a trans- 

 verse direction, and may be compared to a set of shields 

 placed transversely and strung together ; in the longer 

 ramus the segments are longitudinally oblong ; in both 

 they are thickly covered with spines. Second cirrus; the 

 anterior ramus is a little broader than the posterior ramus, 

 with the segments bearing about five rows of bristles ;
