Ibider Hu* microscope the worm maintains a restless movement. 
Kven wlien ils movements are impeded by a mesh o|* cotton wool il 
is never slid, and if is a mailer ot iiiik'Ii diHicidty to make out ils 
inlernal structure. l uder such conditions, moreover, the branchial 
appnralus is greatly refracted. I am able, therefore, at I lie present 
lime, to stale bul little concerning ils anatomy, The number of 
“contract i le loops” could not be certainly determined, bul seemed 
not lo exceed two pairs; while a gastric enlargement, as distinct 
from a succeeding intestine, was likewise not to be readily distin- 
guished. Nor could I certainly recognise reproductive organs, al- 
though these might have been expected to have been developed, 
since my specimens were taken at the end of the summer season 
and, as already noted, budding did not appear lo be taking place 
at all freely. II is of course possible Hint the modification of the 
body in the region of segments 27-29 is not evidence of incipient 
budding bul may represent a clitellar thickening, though such a 
position for the clilellum would seem to be unusually far buck. In 
Bourne's figures (’91) the budding region lias seta 1 developed from 
the Mrs! cul I ing-olT of the new segments apparently, whereas in my 
specimens sehe seemed missing here. II is to be remarked that this 
thickened region was seen in relatively lew specimens, all presum 
ably mature, since I hey possessed wind is apparently the maximum 
number of segments, viz. 7b. 
The terminal “palpi” are not, in this species, markedly longer 
than the branchiae, whereas in />. j'urvala, as figured by Bouslield 
(op. <•//., figure IS), the palpi are shown more than twice as long as 
flic branchhe. 
Bouslield slated, as his opinion, I hat Beidy’s species Anlophvrus 
rin/iis is identical with the Dvro jiu'cala ol Oketi, dillering merely 
in that the worm found by Beidy was free. I have, been unable- to 
refer to Bcidy’s work, but find (hat Pratt, in a “Manual of Pommon 
Invertebrate Animals” ( lb), reproduces a figure by Walton (9b) 
of /). ratjn Beidy, which figure suggests a much shorter, stouter 
worm than IK fun-ala. In this manual !K vtuja is said to consist 
of 2b lo bb segments. Bouslield delines I). firrcatu as possessing 
bb segments and as tube-inhabiting. The Western Australian form 
has 7b segments, and has been found but once in a tube. All 
three agree, however, in a cephalisal ion differing from the remain- 
ing species of Dcro, in that in the latter the dorsal seta? begin in 
(lie sixth segment, whereas in these three species the most anterior 
dorsal set so are found in the til'll) segment. All of these three 
species, too, are peculiar in the possession of paired terminal palpi. 
Bourne (op. e/7.) remarked upon this anomalous eephalisation 
in IK furcaUt (to which Bouslield had directed attention) and stated 
fhal, in his opinion, the character was one of sufficient importance
