laterad, there being in reality no appreciable differences when closely 

 compared, except in the much narrower cariuic of the female specimen.

Whicli, if either, of the preceding two species is that referred to by 

 Porat can not be determined with certainty from his brief remarks : 



"Kamerun, Kitta: Sjostedt; 4 specimens." 



"The apc'cimens from Kamerun are of .smaller si;;e, 60 mm. long, 10-11 mm. broad; 

 the males have, nevertheless, between the first pair of legs of segment 6 and on neg- 

 ment 15 the peculiar processes which I'eters has indicated, and his description 

 applies very well to the above individuals, so that thi- identity is estaiflished beyond 

 doubt. Our specimens are, however, uniformly yellow, probably bleached in alco- 

 hol. Peters gives the color as dark reddish brown, with yellow cariu:e, legs, and 

 antenme." 



After an examination of Peters's type of mossambicns it appears 

 equally certain that the Kamerun specimens do not represent that 

 species. As may be seen by a comparison of the descriptions of the 

 larger forms, the processes of segments G and 15 may coexist with a 

 considerable variety of other characters, while tlie greater part of the 

 remainder of Peters's extended description will apply to any member of 

 the Gomphodesmida', it being, of course, impossible that dift'erential 

 characters could be selected in the description of the first member of 

 what is probably a group of con.siderable extent. 



A recent opportunity of examining fresh specimens of mossambicm 

 in the Hamburg Museum sliows that tliat si)ecies is in reality deep red 

 in color, while all Kamerun specimens yet known are yellow.

Smaller and less convex than T.Jiylinus. 



Vertex smooth and even, without hairs; the sulcus slight; the suture 

 distinct, not colored; head otherwise as in Jiglinus, eKC(i\)t that inferior 

 corners are somewhat more rounded. 



Antenn* filiform, rather slender, the joints not so strongly obconic 

 nor so densely hirsute; the sixth joint not exceeding the fifth and 

 slightly shorter than the third; the last joint is proimitioiially some- 

 what larger than in T. figlinus. 



First segment subelliptic, with a distinct lateral side; less convex 

 and proportionally somewhat longer tbau in T.Jujl'muH; the lateral con- 

 vergence of the sides is considerably less, and the lateral side is not 

 produced and rounded, but has a distinctly longitudinal marginal cal- 

 lus and nearly straight lateral edge. The marginal callus is di.->tinctly 

 narrower than in T. figlinus, and the posterior edge is scarcely emargi- 

 nate in the middle.
