Kramer. The two first-mentioned species are congeneric, Init the otlicrs arc 

 evidently to be referred to Dendrolaelaps Hallit., described in 1915 25, \k G8), 

 with I). Owlemansi as the type-species. In the male of tliis genus the 

 sternnni is separated from the ventro-anal shield, and the lattei' is fused with 

 the second dorsal plate. The chelicerae carry long processes, and the second 

 legs are very stout, the tarsi being armed with a spur. Dr. lierlese has since 

 raised Gamasellus to generic rank, and has established a new sub-genus as 

 follows : — Digamasellus, " Characteres generis Gamasellus, sed scuto maris 

 sternale ab anale distincto. Species typica. G. pcrpiisillus" (9, p. 234). It 

 woidd seem that a new species of Gamasellus found on the rocky shore at Mala- 

 hide is to be referred to the sub-genus Digamasellus. At first 1 had some 

 doubt on this point, but Dr. Berlese lias seen specimens of both se.xes, and 

 refers them to this sub-genus, notwithstanding the fact that the second legs ai'e 

 unarmed on the male, while in the type species (Z>. perpiisillus) they are armed; 

 therefore the present species is e.\ceptional in this respect. 



Gamasellus inermis sp. nov. (PL XXI, fig. 2 a, d.) 



An active orange-coloured species, which lives in fissures and between 

 flakes on the seashore. Female (fig. 2 a): length, 470;u ; breadth, 264/ii; 

 colour a shining orange ; immature specimen yellowish. Body of the usual 

 gamasoid shape, with three double rows of short hairs. Dorsal plates of 

 almost equal breadth ; the truncated posterior margin of the second plate 

 reaches end of abdomen, and carries a pair of large pores (fig. '2 b). Sternum 

 long, with bow-shaped front, and truncate end margins, sides <leeply incised. 

 Jugular plates absent, at least as separate plates; metasternal plates rudimen- 

 tary, position indicated by paired hairs. Genital plate laelaptoid, longer than 

 broad ; a pair of hairs on the side margins. Yentro-anal shield large, flattened 

 on its front margin, and it reaches the end of the body in some specimens. 

 Inguinal shields are present, and there are also three or four pairs of very 

 minute plates. Endopodial plates rod-like. Peritreme strongly sinuate, 

 poststigmatic end partly encircling last pair of legs. 



Capitulum quadrate, epistome with three short spines, ma.xillary lobes 

 acute, and placed well in advance of the palp articulations, Free chela armed 

 with two strong teeth, fixed chela with two teeth, and a smaller one placed 

 near extremity. Palps (length 125;u) of normal structure, the second and 

 third segments armed on their inner sides with a strong spine. Legs rather 

 long and stout, with sparse hairs; the approximate lengths are 34();u, 286;li, 

 242/x, 298|u. 



Male: Considerably smaller than the female, with which it agrees in the 

 structure of the dorsal plate, peritreme, pedal plate, and other characters.
