4 Prof. M'Tntosh's Notes from the 



tlie desiccation. What appeared to be tlie anterior end 

 presented two rounded processes with a slit (mouth?) betwecu 

 them. Tliis area was followed by six or seven narrow rings, 

 each increasing on its predecessor. Behind these the seg- 

 ments were wider, and hy-and-by showed two rings. The 

 body seemed to be somewhat fusiform in outline, diminishing 

 at each end, the posterior rfgion presenting narrower rings. 

 A groove occurred on each side anteriorly and })roljably 

 continued to the posterior region, but the condition of the 

 examples rendered this ambiguous. In this groove were 

 the branchia>, which appeared to extend almost from end to 

 end, arising in fiont of the bristle-tufts and foi'ming elavate 

 organs (in the dried condition) of some length. The state 

 of the specimen precluded absolute accuracy in tlys resi)eet, 

 and also as to whether some may have been bifid. They 

 sprang from the anterior edge of the fold of the segment 

 somewhat below the bristle-tufts. The entire surface of the 

 body was covered with a tough (almost ehitinous) enticle 

 minutely reticulated, so that under a lens it resembled very 

 line shagreen. Under the microscope rounded areas with a 

 clelinite rim appeared. 



The pale golden bristles formed two separate tufts in each 

 segment, the dorsal consisting of long, tapering, simple 

 bristles (PI. I. fig. 2) similar to those in EuineJiia crassa, 

 but having no bifid spinous forms amongst them. 



The ventral tuft, again, has long bristles (PL I. fig. 1) 

 and the tip (PI. 111. fig. 6) of similar shape, but closely 

 spinous throughout the distal third or more. When covered 

 with debris or the crystalline rods found in old spirit-prepa- 

 rations, these spines may be overlooked, though it was the 

 regularity of the crystalline rods which at first directed 

 attention to these spikes. 



So far as known no Enmenia or Lijmbranc/ius presents 

 the features of this s])ecies, sim])le bristles finely ta})ered at 

 the tip and shorter bifid spinous bristles characterising the 

 known forms. Moreover, the presence of branehiai through- 

 out the body is another feature of moment, and in this it 

 agrees with 7:'. hystricis. 



Genus Fauveliopsis, nov. 

 Prostomium rudimentary ; cephalic region blunt, with 

 bristles on each side, liody definitely segmented, divisible 

 into anterior, middle, and posterior regions and grooved 

 ventrally. Dorsal and ventral bristles with a })ear-shaped 

 pai)illa between them. The stouter anterior bristles present 

 a terminal Imok.
