GONIADA EEEMITA. 467 



runs from end to end, and with the feet deeply cut. The first sixty-six feet are uniramous 

 three-lobed, with a lanceolate or sausage-like dorsal and a lanceolate ventral cirrus. The 

 feet behind have two divisions, the upper with a leaf-like dorsal cirrus, a lanceolate lobe, 

 and simple bristles ; the inferior division boldly trifid, with a lanceolate ventral cirrus and 

 compound bristles. Proboscis armed distally in extrusion with two large black teeth, 

 each with a flattened base, a short curved and blunt process, and three curved teeth, 

 whilst a belt of numerous spiked and complex denticles (somewhat ^-shaped) occurs 

 between them. Feet proportionally longer than in G. maculata, and from about the 

 tenth have five processes, viz., a dorsal cirrus, a three-lobed spinigerous region, and a 

 ventral cirrus. A change occurs at the sixty-ninth foot, the seventieth being biramous.

Habitat — Specimens dredged in the ' Porcupine ' Expedition of 1870 in eighty-one 

 fathoms off Cape Finisterre, and in forty-five fathoms (eight miles N.W.) off Cape Sagres. 



The head appears to be somewhat less attenuate than in the common form, but this 

 may have been partly due to the complete extrusion of the proboscis. 



Body somewhat larger and longer than in Goniada maculata, of a firmer consistence, 

 more rounded dorsally, and grooved ventrally. First two segments without feet, the first 

 the broader. Proboscis (Fig. 88) with fifteen to eighteen V-shaped teeth on each side. 

 Rounded keel of the great fang less, and the adjoining flattened plate proportionally 

 longer ; terminal fang more massive, and the smaller teeth behind it fewer in number. 

 The row of spiked ^-shaped denticles is at least four times as numerous as in G. maculata. 

 Anteriorly the feet are proportionally longer than in G. maculata, and about the tenth 

 (Plate LXXXVII, fig. 20) have four lobes or papillse, viz., a large lanceolate dorsal lobe 

 (cirrus), which arises on the dorsal edge, nearer the base than the other processes, and 

 has a constricted base ; a larger and longer digit-like posterior lobe ; and two slightly 

 shorter anterior lobes which occur at the spinigerous region, whilst below is the long 

 lanceolate ventral lobe or cirrus. Only compound bristles are present. This therefore 

 differs from the condition described in Goniada maculata. At the thirteenth foot the 

 dorsal cirrus is a long sausage-shaped structure with a constricted base, and it has now 

 receded toward the body. 



A considerable increase in length of the foot and its processes takes place at the 

 twentieth foot, the dorsal cirrus arising near the base, its tip reaching outward dorsally 

 to the middle of the foot. The long, pointed posterior lamella is prominent, and of the 

 two smaller anterior processes the inferior is the less, the lanceolate ventral lobe or cirrus 

 extending beyond the rest. At the thirty-first foot a single spine and only compound 

 bristles are found, as in front, and so at the fiftieth foot. Immediately behind the fiftieth, 

 however, a change occurs, two processes appearing instead of the single cirrus dorsally. 

 In the example this took place at the fifty-third foot, a lamella being suddenly developed
