124 REV. O. P. CAMBRIDGE ON SOME NEW [Jail. 21, 



of this Spicier, I have received numerous examples of both sexes in 

 the adult state from Ceylon, kindly sent me by Mr. Nietner, as well 

 as by Mr. Thwaites. 



The adult male resembles the female in general characters, colours, 

 and markings, but is rather smaller ; the caput is also rather more 

 produced ; and the abdominal spines are longer in proportion than 

 those of the female, in fact exceeding in length that of the abdomen 

 itself, and presenting a very formidable appearance, an absolute bar, 

 one would imagine, to any chance of ever being swallowed by a bird. 

 The palpi of the male are dark brownish black; the radial is rather 

 longer and stronger than the cubital joint, and is broadest at its fore 

 extremity, where it has a marginal row of bristly hairs ; the digital 

 joint is moderate in size, and of an oval shape ; the palpal organs 

 are well developed and encircled with a slender filiform spine. 



Phoroncidia brevispinosa, sp. n. (Plate XIV. fig. 7-) 



Female adult, length 1 line. 



This species nearly resembles P. thwaitesii (Cambr.) in its general 

 form and in the number and position of the spines on the abdomen; 

 but it may be distinguished easily by its smaller size, the shortness 

 of the spines, and the less prominent ocular portion of the caput. 



The cephalothorax is of a blackish-brown colour : the legs pale 

 orange-yellow, short and rather strong, their relative length being 

 1, 4, 2, 3 ; the difference between 1 and 4 is very slight;. and they 

 are furnished spariugly with bristly hairs. The palpi are also short, 

 similar in colour to the cephalothorax, and apparently without any 

 terminal claw. 



The eyes do not differ greatly in size ; but their position is the same 

 as that of P. thwaitesii, four centrals forming a square ; and on 

 either side the laterals are placed very obliquely, almost horizontally 

 in fact, and forming with the fore centrals nearest to them a short 

 curved row on each side. 



The colour of the falces, rnaxillce, and labium is dull yellowish 

 brown, and that of the sternum nearly black. 



The abdomen is of a dull orange-yellow colour, with a few small 

 indistinct whitish patches ; its surface is thinly but regularly, and 

 (on the upperside at least) somewhat symmetrically, covered with 

 round impressed dots or punctures; there are also a few small 

 blackish spots on the upper part, hinder part, and sides ; and the 

 posterior spines are clouded with black. 



The spines, nine in number, are very short, and, in fact, of a sharp 

 conical form ; but their position is exactly the same as in the spines 

 before alluded to in P. thwaitesii. 



A single adult female was received from Mr. Thwaites in 1871. 



Phoroncidia septemaculeata, sp. n. (Plate XIV. fig. 8.) 



Female adult, length 1 1 line. 



The excessive elevation of the abdomen, whose height is double 

 its length, will serve readily to distinguish this species, indepen- 

 dently of the very different nature and the number of the spines :
