Of the examples mentioned by Loman, as coming undei" 

 this genus, it should be noted that all except the genotype 

 H. viridintestinalis agree in lacking auxiliary claws, it 

 may later be necessaxy to amend the generic definition to 

 include these species, but they should be first examined to 

 verify their descriptions with regard to this particular 

 character. The presence of a-uxiliary claws when very 

 small was often overlooked by earlier writers. 



The following emended definition of Halosoma is based 

 on the characters exhibited by //. hasiveUi and H . viridin- 

 testinalis. 



HALOSOMA, Cole (1904), emend. 



Trunk rather stout, crurigers broad, more or less 

 closely crowded, neck little developed, prohoscis cylindri- 

 cal or nearly so, large, -issuing ventrally from the 1st seg- 

 ment. Chelifori well developed but slender, chelate. 

 Palps absent. Ovigers, in female absent, in male 6 jointed, 

 ultimate joint devoid of terminal claw or specially de- 

 veloped spines, much smalleir than penultimate^. Legs 

 rather stout, propodus with expanded heel with a few 

 large spines, sole with well developed spines. Claw well 

 developed, auxiliary claws minute but distinct. 



Genotype: — Halosoma viridintestinalis, Cole (1904). 



3. Halosoma haswelli, sp. nov. 

 (PI. I., figs 1-6.) 



Description. — Trunk fairly broad, all segments united, 

 •sutural lines not distinct dorsally, but more distinct ven- 

 trally, first segment almost twice as long as second, 

 crurigers in contact proximally, but diverging somewhat 

 ■distally, crurigers about as long as broad ; neck very short. 



Ocular tubercle of medium length, rounded, shorter 

 than caudal segment, placed mesially almost at anterior 

 margin of first segment, apex pointing anteriorly ; e3^es 

 large. 



Caudal segment of medium length, longer than ocular 

 tu.bercle, apex roiunded, almost erect. 



Proboscis large, almost cylindrical, arising from ven- 

 tral side of first segment, extending forward and slightly 

 downward, increasing slightly in diameter from base to 

 apex; anterior end truncated, lengtih about half that of 

 trunk, slight circular constriction present near anterior 

 ■end of proho'Scis. 



Chelifori well developed, scape smooth, one jointed, 

 projecting slightly beyond the end of proboscis, clavate;
