over the lamina bulbi, and terminating externally with a blunt tooth, 

 and under the apex of which issues a fine curved spine. Under 

 pressure, seen through the microscope, the joint closely resembles the 

 figure given of it by Menge loc. cit. 



Ohlert has kindly given me specimens of his Micryph. capito. 

 Cambridge has sent me an English specimen of Wahkm. hiemalis 

 Blackw., which species Walckenaek (Ins. Apt., IV, p. 510) erroneously 

 classes under his Argus cucullatus.

Though Blackwall does not mention the opaque, rugous sur- 

 face of the cephalothorax, I nevertheless look upon his synonym as 

 certain, for Blackwall's description of the remarkably characteristic 

 palpi of W. obscura exactly agrees with Westring's spider, of which 

 1 have the type-specimens in my collection. Cambridge also writes to 

 me, that he is of the same opinion. — The palpal clava is large, very 

 complicated; the back of the lamina, viewed in profile, is serrulated 

 from the base to before the middle , where it forms a ledge or coarse 

 tooth; from the neighbourhood of the base of the bulbus, on its 

 inner side, proceeds a very long, fine spine directed backwards and 

 afterwards curved downwards and forwards, which is longer than the 

 entire clava.

1 have not met with this species in any other writer than 

 Westring, who has favoured me with the type-specimen to his ex- 

 cellent and fully sufficient description.
