Body Segments. — The type specimen shows the inside of the tergites of the first 

 four segments. The specimen does not, however, extend far enough to show the mar- 

 gins of any of these segments except the first. This segment is only half the length of 

 the succeeding ones [i.e., 9 mm.), and extends laterally some 15 mm. beyond the angles 

 of the carapace, which would make the total width of the segment more than 130 mm. 

 Of the other segments in this specimen nothing can be made out except that they are 

 band like sclerites, measuring some 18 mm. from front to back. A small portion of the 

 ventral surface is shown on a small island towards the right side. One of the specimen* 

 referred to in my former paper shows the ventral surface of all the body segments of a 

 specimen, the total length of which, without the telson, must have been between 550 

 and GOO mm. (PI. IV., fig. 24.) 



Appendages. 



1st pair. (PL V., fig. 26.) — The position of the chelicerse can be made out on each 

 side, the middle line commencing 10 mm. behind the anterior margin, and having a 

 length of 12 mm., and a breadth of about 5 mm. at the base. They are somewhat 

 conical in form, the apex of the cone being directed backwards. They agree in all 

 essentials with the corresponding appendages in E. scorpioides and other forms. 



2nd pair. — This appendage projects some 22 mm. beyond the anterior margin of the 

 carapace on the right side. The number of joints cannot be ascertained. The last joint 

 ends in a powerful pair of curved spines very broad in proportion to their length. The 

 penultimate joint carries a spine on the inner side, and another rather doubtful spun 

 lies immediately in front of the carapace. 



3rd- 5th pairs. (PL IV., fig. 23. PL V., fig. 26.) — The next three limbs resemble one 

 another in being powerful, curved organs armed with a double series of curved spines 

 along the anterior margin of the four distal joints. The terminal (7th) segment bears a 

 pair of particularly powerful spines, and the strongest spines on the 5th and 6th joints 

 appear always to arise from the distal angle ; indeed, it is doubtful if these joints bear 

 any spines beyond the one pair. The 4th joint bears, at all events, in the 3rd pan of 

 appendages, three or four moderate sized spines. The spines themselves arc smooth 

 except when occasionally an extra large one shows signs of longitudinal striae. The pro- 

 portion of the joints to one another seems to be slightly different in the different pairs, 

 but I have not been able to get any certainty as to which is which. 



6th pair. (PL IV., fig. 23.) — Only one fragmentary specimen of this has been found. 

 It probably belonged to an individual slightly larger than the type. The last two joints 

 only are preserved, and of these the penultimate is a good deal broken. It (the penulti- 

 mate joint) is very broad (40 mm.) and comparatively short (45 mm.), but presents no 

 points of special interest. The terminal joint is oval in shape, comparatively long 

 (63 mm.) and narrow (25 mm.). It narrows towards its point of articulation. The 

 posterior border is marked along the distal third of its length by a series of four oblinue
