IIG Prof. M'Intosli's Notes from the 



Finisterre ; Isocirrus D off Cape Guardia ; a fragmentary 

 Leiochone near B in 795 fathoms at Station 17 « ; and 

 Pseudoclyniene I in 25 fathoms in Bono Bay. Ehlers ^ 

 mentions a fra^^ment of a ]Maldane, Praxilla mvUeri, Sars, 

 and Praxilla nigrita, sp. n., as occurring in this Expedition. 

 The latter form appears to be allied to Leiochone, but the 

 figures of the hooks are indefinite, and one of the bristles of 

 the posterior feet differs from most forms in so far as the 

 spikes on the terminal region point backward. 



The first of these is a fragmentary Praxillura ? (A), dredged 

 in the Expedition of 1870 at Station 8, lat. 48° 13' N. and 

 long. 9° 11' W., at a depth of 257 fathoms on the Channel 

 slope in the midst of a northern fauna. 



The cephalic region of this small form is abruptly trun- 

 cated, the frontal edge being produced into a flattened and 

 somewhat spathulate snout with a rounded anterior border. 

 A slight keel occurs on the truncated surface. The anterior 

 end is flexed in the example, and behind the mouth is a 

 deep furrow. The body is long, slender, and apparently 

 brightly coloured in life, and terminates posteriorly in a 

 somewhat tapered tail which ends in a blunt cone with the 

 anus dorsal. About three or four unarmed segments occur 

 posteriorly. So far as could be observed, only three segments 

 anteriorly bear hooks and bristles, the third pair of hooks 

 being remarkably strong for a form so slender. 



The typical hook (PI. II. fig. 1) is minute, with a mode- 

 rately long curved shaft, a marked shoulder, proportionally 

 large great fang which makes rather less than a right angle 

 with the neck, a single gular bristle which arises after an 

 interval from the throat, and four teeth on the rather elevated 

 crown. The line between the base of the great fang and the 

 origin of the gular bristle is incurved, and the neck has a 

 considerable inclination backward from the shaft. The 

 bristles consist of stouter winged forms with tapering tips 

 and more slender bristles Avith hair-like tips. So far as 

 could be seen, both had smooth edges. The tube consisted 

 of secretion with grains of sand and minute fragments of 

 shells. 



Praxillella pratermissa, var. ? 



A form dredged in the ' Porcupine ' Expedition of 1870 in 



25 fathoms in Bono Bay differs irom the ordinary type in its 



smaller size and in the shape of the anal funnel. It is in a 



tube of sand-grains loosely connected to a central lining of
