the apex. Mesopleurse coarsely rugosely punctured. Meta- 

 pleurse longitudinally striated, the striae weaker at the base. 

 Wings fuscous violaceous, the hinder pair paler thau the 

 anterior ; the stigma and nervures dark fuscous ; the third 

 transverse cubital nervure is interstitial, with the nervure 

 bounding the top of the radial cellule ; the latter is clearly 

 separated from the radius. Legs thickly covered Avith white 

 hairs ; those on the tarsi have a fulvous hue. Abdomen 

 shining, sparsely minutely punctured ; the pygidiura is more 

 strongly punctured, except on the apex ; the ventral surface 

 is sparsely covered with white hair. 



A distinct species, not nearly allied to any of those already 

 described. It is one of the largest species.

In an ordinary way it would not be necessary to make any 

 reply to Dr. Dahl's " One Word more on the International 

 llules of Nomenclature " (Zool. Anzeiger, Bd. xxv. Feb. 

 1902), for he considers this to be the last word. Since, 

 however, he asks for some answer to his questions, and has, 

 as he says, taken up his pen for ray special enlightenment, 

 it would be uncourteous were I to refuse to return the 

 compliment. 



In the first place, Dahl complains that I am upsetting the 

 unanimity which has hitherto prevailed as to the types of 

 genera, and quotes Gnaphosa^ Micromata, and Salticus as 

 instances. In the case of the last genus, however, Simon, in 

 the latest part of his Hist. Nat. Araignees, gives scem'cus as 

 the type; whereas Thoreli and nearly all authors, including 

 Simon himself, have hitherto regarded formicarius as the 

 type. I might add a few more instances, Thoreli gave 

 sisj/phium, Clerck, as the type of Theridion; Simon gives 

 redimitum, Linn. Simon restores Araneus ; Thoreli, until 

 quite lately, upheld Epeira. Thoreli again gives us lugubris^ 

 Walck., as the type of Lycosa ; Simon gives us tarentula, 

 liossi. Thoreli regarded mirahilis, Clerck, as the tyj>e of 

 Ocyale ; Simon gives us atalanta, Aud., &c. &c. So much 

 for the prevailing unanimity. But I may be permitted to 

 suggest that Dr. Dahl need not exercise himself over tlie 

 iniquity of changing a name or two here and there, seeing
