456 LYSIDICE PUNCTATA. 



Grube (1870), who examined the specimens in the Parisian Museum, showed that the 

 Blainvillea of De Quatrefages was a Nematonereis. 



Nematonbebis sp. Plate LV, figs. 7 and 8— head and tail ; Plate LVI, fig. 6— body. 



A form sent by Dr. Allen from Plymouth differs considerably in outline from the 

 foregoing, and is much less rigid, yet the general structure appears to agree. The loss 

 of the example by the artist after delineation prevents a satisfactory decision. This form 

 is considerably paler than that from the Channel Islands, has about seventy segments, and 

 the tail (Plate LV, fig. 8) has two shorter and two longer cirri. The head (Plate LV, 

 fig. 7) agrees with V. unicornis, and the dental armature is similar, but the feet are some- 

 what longer and more conspicuous and the spines are dark. The colour anteriorly varies 

 from pinkish to pale green, then the intestine gives a brownish hue to the central region 

 whilst the posterior region is brownish-yellow. 



KinbergV third family of the Eunicea is the Lysidicea, distinguished by seven 

 maxillas, part Ii edentate; three tentacles, neither antennge nor palpi; buccal segment 

 double. Of the genera — Amphiro and Lysidice— the former is distinguished by the 

 presence of pectiniform branchiaa, whilst the latter has none. 



Genus LXXIII. — Lysidice, Savigny, 1820. 



Head free from the buccal segment, bearing three tentacles and two eyes ; two large 

 palpi. 



Feet with cirri, bristles, and spines. 



1. Lysidice punctata, Bisso. Plate LV, fig. 3; Plate LXIII, figs. 6 and 6 a — teeth; 2 

 Plate LXXV, figs. 4-4 b— feet; Plate LXXXIV, figs. 2-2 a\ and 9— bristles. 



Specific Characters. — Head broad and flattened, with a median notch anteriorly, 

 while inferiorly are two thick prominent palpi. Median tentacle is short and somewhat 

 fusiform, tapering distally, and situated rather in front of the lateral. Eyes two, 

 black, of considerable size. Colour pale brownish, dappled with pale dots. Body 6 — 7 ins. 

 long, tapering a little anteriorly, but more distinctly so posteriorly, where it terminates in 

 four caudal processes. The first three segments are of a deeper brown hue and dappled 

 with pale spots. First and second devoid of feet. The fourth segment is pale or whitish 

 anteriorly, and in some the whole segment is white (Ehlers). The brownish colour with 

 pale dots continues to the twentieth or twenty-fifth segment, and then fades into the 

 paler brownish iridescence of the succeeding region. Segments in the middle and 

 posterior part of the body boldly marked. 



Proboscis has strong, curved maxillas, with a shoulder posteriorly and long posterior 

 appendages with a notch in the middle. Great dental plates have four prominent teeth 

 on each side anteriorly — the anterolateral plates. The mandibles are proportionally
