triangle, on the middle of the forepart, and two large, somewhat tri- 

 angular patches, one on each side, between the two anterior angular 

 prominences, of a cream-yellow colour ; the hinder part of the 

 abdomen is of pale yellow-brown hue, mottled with blackish brown 

 near the darker surface of the fore part. Another example was 

 somewhat similarly marked on the abdomen, but had an altogether 

 yellowish hue, the cephalothorax, palpi, aud legs being yellow, 

 without any markings or annulation whatever. A third example has 

 the abdomen of a shorter form, more convex above, and the posterior 

 conical eminences very much smaller and shorter, scarcely larger 

 than the anterior ones. The whole of the upper surface and sides 

 are of a dull cream-colour, with four dark reddish-brown spots 

 in the form of a trapezium in the middle, and a few veiny lines of 

 the same hue : also at the fore extremity is a dull reddish-brown 

 transverse band, and a few irregular markings of the same colour on 

 the sides ; the legs and palpi are annulated. I am more than half 

 inclined to think this example may be of a different species ; but at 

 present it will be best to leave it where it is. 



An adult male accompanying the above three examples is rather 

 smaller, the abdomen much more flattened, of a uniform deep 

 reddish black-brown, with a few obscure yellowish spots and markings 

 on the upperside, and the posterior prominences intermediate in 

 length and strength between those of the first and second of the 

 females above described ; the caput is more elevated and prominent, 

 and the cephalothorax is of a uniform dark red-brown colour. The 

 palpi are rather long and strong ; the cubital joint is short and bent, 

 the radial shorter but prominent behind; the digital joint is very large 

 and of ordinary form, its convex sides are directed inwards ; and 

 the palpal organs are rather complex and encircled by a strongish 

 spine. 



The examples above described of this interesting little Spider were 

 sent to me by Capt. F. W. Hutton, from the west coast of Otago, 

 New Zealand. I am not satisfied with respect to the generic position 

 here given to this Spider, which has a close affinity to Phoroncidia, 

 Westw., as well as to Stegosoma, Cambr. 



Fam. Thlaosomides. 

 G-enus Thlaosoma, Cambr. 

 Thlaosoma atkinsonii, sp. n. (Plate LII. fig. 7.) 



Adult female, length 3 lines, breadth of abdomen at the widest 

 part 3| lines. 



The general form of this Spider resembles very nearly that of 

 others of this curious genus, but it may be readily distinguished by its 

 colours and markings as well as by the special form of the abdominal 

 protuberances. 



The fore part of the caput is upturned, ending in a subconical 

 point, and bearing the four pairs of minute eyes, in the usual position. 

 The colour of the cephalothorax is of a whitish-yellow or pale 

 cream hue, marked on the sides with dusky yellowish brown, leaving
