54 Prof. M'lntosh's Notes from the 



belong to a small species about an inch or a little more in 

 length. Thus the cephalic plate and collar were so injured 

 that all that can be said is that the ventral edge of the 

 collar was rather full and the two sides separated only by 

 a narrow fissure ; but no reflection seemed to occur. The 

 lateral regions appeared to be entire up to the dorsal edge. 

 Dorsally in every instance the parts adhered to the tube, 

 and the collar seemed to be rudimentary. Behind the 

 ventral collar were two inner curved ridges surmounted by 

 the bases of the branchiae. The branchise in the preparation 

 were pale and about ten in number in each fan, the pinme 

 being of moderate length and continuing nearly to the tip, 

 which in some was blunt, in others with a short subulate 

 process ; but the preparation was unsatisfactory, the tips 

 being incurved and adherent to the tube. The anterior 

 bristles are pale golden and in two groups — a dorsal longer 

 series, few in number, with straight shafts and finely tapered 

 winged tips (PI. 11. fig. 1), and a more numerous series, with 

 oar-like tips from tlie breadth of the wings (PI. II. fig. 3), 

 some having and others not having a slender median prolon- 

 gation of the axis at the tip. The tips of the small posterior 

 bristles are much elongated, especially dorsally, and have a 

 distinct curve. Narrow wings occur in the longer and 

 bi'oader in the shorter forms (PL II. fig. 2). The anterior 

 hooks (PI. I. fig. 10) have a rather high crown, which is 

 often indicated by a transverse line, a long neck, and a 

 wide gulf anteriorly, whilst the posterior outline is nearly 

 straight except the forward curve at the crown. The base 

 forms a wide angle with the posterior outline, and the prow 

 is only moderately prominent. The base is comparatively 

 short. Numerous small teeth occur above the main fang. 

 These hooks are accompanied by a series of short bristles, 

 the tips of which in certain views looked like an elephant's 

 foot from the thickness of the shaft, though in most views 

 the tip ended in a point (PI. I. fig. 11). The posterior hooks 

 are smaller, but retain the characteristic features of the 

 anterior. 



The tube is composed of fine grains of sand mixed with a 

 number of minute Foraminifera.
