 Genus Hadruroides, Pocock. 



Dr. Kraepelin, in tlie ' Tierreich,' admits only one species 

 for this genus, giving- the following- list of synonyms : — 

 ]i. hniaiiis, L. l\oc\\, = 7naculatus, Thor., parvulus, Karsch, 

 cJiorcosiis^ Karsch, Paaschi, Karsch, and rohustus, Boeris. 



Although I have had no opportunity of examining the types 

 of any of the forms bearing the names given above, I do not 

 doubt that Kraepelin has confused at least two species, and 

 very possibly more, under the name //. lunatus. One of these 

 is the true i/. haiatiis, which, judging by L. Koch's admirable 

 description, is re|)resented by several Peruvian specimens in 

 the British Museum. A second is what may be provisionally 

 called //. cJtarcasus ; H. maculatus is probably a third. 



Hadruroides lunatus, L. Koch. 



Telef/onus lunatus, L. Koch, Verb. z.-b. Wieu, 1867, p. 235. 

 Hcnlntroides lunatus, Kraepelin, Das Tierr., Scorp. p. 188 (1899) (iu 

 part). 



$ . — Colour yellow ; carapace and terga lined with black, 

 each tergal plate marked with four black spots, one narrow on 

 each side of the middle line and one broader near the lateral 

 margin. Closely allied in structural features to the species 

 described by Kraepelin as H. lunatus of L. Koch, but con- 

 siderably smaller, with the inferior lateral keel of the fourth 

 caudal segment smooth ; the hand entirely smooth and 

 narrower, its width in the adult being only equal to half the 

 length of the carapace ; the fingers when closed are distinctly 

 separated at the base by an excavation on the immovable 

 finger. Pectinal teeth 11-12. 



^ . — Smaller than female, with frontal area and abdominal 

 sterna finely and closely granular, pectinal teeth 14-15, and 

 a considerabl}' larger notch and lobe on the base of the im- 

 movable finger. 



Measurements in millimetres. — $ . Total length 45 ; length 

 of carapace 6, of tail 2.5. J. Total length 37; length of 

 carapace 5, of tail 23. 



Loc. Peru (without further history) ; two adult males and 

 four adult females. Also a single female from Callao. 



Kraepelin appears to have mistaken this species for the 

 young of the form described as //. charcasus by Karsch. 

 H. macvlatus, Thorell, can scarcely be synonymous with this 

 form, since Thorell expressly says : — " segmentum ventrale 

 ultimum costis duabus tenuibus utrinque munitum.'^ And
