ChelopJwres are remarkable in shape. The shafts of 

 the two chelophores arise from the anterior margin of the 

 abbreviated cephalon, but are separated from one another 

 by a distinct interval. The division of the scape 

 into two joints is not apparent in the holotype. 

 Each scapo is longer than the proboscis and is quite 

 narrow at the base, but expands distally to form 

 a oup into which the terminal portion of the scape 

 is involuted. To the bottom of this cup on the inside is at- 

 tached the chela. The rim of the cup has a characteristic 

 armature consisting of a series of some eight spines. Of 

 these spines those of the ventral poition of the rim are 

 short and simple, those on the dorsal side being larger and 

 possessing each at its base a pair of short auxiliary soines. 

 The chela is delicate; the palm is small, the fingers curved 

 and untoothed. The movable finger is external. The fin- 

 gers enclose a wide space, and their points cross at the 

 apex.. In its natural position the chela is more than half 

 hidden in the cup. The involution is held in place by 

 muscle fibres. It is possible that the chela can be pro- 

 truded. (In the holotype slide the right chela cup has 

 been evaginated, having broken from its fastening evident- 

 ly under the influence of the pressure used in making the 

 slide.) 



Abdomen is a cylindrical tube extending almost ver- 

 tically vipwards. Its posterior side is somewhat concave — 

 on the anterior side, near the apex, is a pair of papillae 

 each bearing a long simple spine. 



Palps are evidently normally nine jointed, although 

 the right palp only possesses eight joints. The palps arise 

 laterally to and below the chelophores'. The following de- 

 scription api^lies to the left palp : — The second and fourth 

 joints are longest, the first and third short. The fourth 

 joint is curved and possesses a distinct tubercle about one- 

 third the distance from the distal end. On this opens the 

 duct of tlie palp gland which lies in this joint (Hoek, 1881, 

 p. 105). The remainder of the joints of the palp are all 

 small, the sixth being the longest of them. It forms an 

 angle with the shorter fifth joint. The seventh, eighth, 

 and ninth joints axe all small. In the palps, the first and 

 second joints axe devoid of spines, the third and fourth 

 have occasional spines and a distal fringe. The remainder 

 of the joints are well provided with spines. 



Ovigers. — It is a matter for regret that in the slide 

 these appendages are so broken that it is impossible to 

 count the joints. One portion which has altogether come 

 apart from the animal consists of seven joints, but this is
