The ventral division has seven hooks and four capillary 
bristles, the two ceutral being longer and stouter than the 
others. The lamelle have long, finger-shaped, amber- 
coloured glands, 
The tail of A. ovycephala in the examples from Herm is 
small, and has dorsally two short conical lobes, whilst be- 
neath are about eight smaller conical cirri, whereas in this 
species there are but two pairs of anal cirri. 
Besides the additional Spionids mentioned in the 
‘Annals’ for January 1915, another form, viz., Magelona 
rosea, Moore, has been dredged by Mr. Southern in Killary 
Harbour in mud. In this the prostomium and peristomium 
are coalesced to form the broad ovoid head (in spirit), with 
dorsal cephalic ridges tapering to acute points, which diverge 
anteriorly. Peristomium with prominent lateral lobes ; ten- 
tacular cirri arising laterally with papillee, which increase in 
length distally. Proboscis soft, bulbous, with parallel strize. 
Body slender, depressed, tapering and subquadrate anteriorly, 
40 mm. long; segments about ninety-five. Ninth bristled 
segment with tapering simple bristles*. Pygidium small, 
oblique, with anus dorsal, covered by a broad flat papilla, 
and with posteriorly a pair of small sleader cirri. Colour 
translucent white, intestine buff or greenish brown, pharynx 
salmon-pink. In sand at and below water. Nearly ripe in 
August. 
The larvae have been described by Fewkes as Prionospio 
tenuis, from Newport, and by Andrews from Beaufort, N.C., 
and Wood’s Hole. 
Under the family of the Cirratulide, Cirratulus chiajii, 
M‘Intosh, has been subsequently described as Cirradulus 
norvegicus, De Quatrefages, but Della Chiaje had long 
before termed it Lumbricus filigerus and Cirratulus filigerus, so 
that if priority held such would be its title. It is perhaps 
doing no injustice to De Quatrefages or other author by 
giving it the title C. chiajii after its early investigator. 
A form termed Cirratulus norvegicus in the ‘ Annals’ for 
February 1911 +, has since that date been named Cirratulus 
mcintosht by Southernt, who found it in Inishlyre, 
Kallary, and Bofin harbours. It is interesting to find this 
Norwegian species in British waters. 
* Unfortunately, the specimen sent by Mr. Southern had no ninth 
segment.
