;U Prof. M'liitosli's Notes from the 



papiUosa. The third scries present narrower wings than the 

 hist, and the tips project little hcyond the surface. So brittle 

 arc the ti|)s that the tapered axis, or terminal re>;ion of the 

 shaft, olten snaps at the base of the winjjj, leaving a trans- 

 parent web forming the wings projecting freely beyond it 

 and on one side of the shaft. This is not common. 



In his aeconnt of the species, Malmgren (18G5) did not 

 refer to other than the anterior hooks, which are rather 

 large, have moderately long and boldly curved shafts, also 

 as brittle as the bristles. These dilate from the base np 

 to the shoulder, then are slightly narrowed at the neck. 

 The main fang comes off nearly at a right angle, and in 

 lateral view has eight or nine teeth above it, but the crown 

 is flat, and thus diflers from such as E. papillosa, in which 

 tlie crown is more elevated. The hooks in the anterior 

 part of the posterior region ai-e avicnlar, have a main 

 fang which leaves the neck at less than a right angle, a rather 

 liigh crown with five or six teeth in lateral view, a convex 

 })osterior border, a prominent and massive prow, and a 

 small basal process posteriorly. The terminal hooks, again, 

 are considerably smaller, have a much higher crown and 

 more numerous teetli in lateral view, and the posterior basal 

 process is smaller. All the shafts of the bristles and long 

 Looks are t>lightly brownish by transmitted light. 



Enchoiie )wrma)n*,&\). n., the thirteenth form, is unfortu- 

 nately fragmentary, and nothing is known of the branehise. 

 Tiie cephalic collar is fairly develoj)ed, with a deej) fissure 

 dorsally, the margin sloping thence downward and forward 

 to the ventral process, a slight projection on each side of the 

 middle line with a fissure between occurring there. The 

 bodi/ appears to be comparatively short, and the anal funnel 

 is short antero-posteriorly and wide, the margin being thin 

 and deep anteriorly with a shallow median notch, whilst the 

 sides are boldly and somewhat regularly crenate for more 

 than the anterior half. The anterior bristles are of two 

 kinds, a longer series dorsally with finely tapered and narrow 

 wings, and those ventrally situated with broader wings 

 and shorter tips. Posteriorly the tips of the bristles are 

 greatly elongated, and the wings very narrow. 



The anterior hooks have a long curved shaft tapering to 

 the base, whilst the neck is narrowed above the shoulder 

 and curved backward. The great fang comes off nearly at a 

 ri'^ht anjjle, and al)ont four teeth are on the crown above it
