towards the spinners. The radial joint of the palpi is larger than the cubital, and the digital 
joint is of an elongated oval form, terminating in a point ; this last joint is convex and hairy 
externally, concave within, comprising the palpal organs, which are globose at the base, with 
a fine, curved spine at their extremity, and are of a red colour. 
Dr. Leach has taken specimens of Atypus Sulzeri in the vicinity of London and Exeter. 
(See the Supplement to the fourth, fifth, and sixth editions of the c Encyclopedia Britannica/ 
article “Annulosa.”) It excavates, in humid situations, a subterraneous gallery, which is at first 
horizontal, but inclines downwards towards its termination. In this gallery it spins a tube of 
white silk, of a compact texture, about half an inch in diameter, and the female deposits 
between thirty and forty eggs in a cocoon of white silk attached to its extremity. Part of 
the tube hangs at the outside of the aperture to protect the entrance. 
Since the instances of the capture of Atypus Sulzeri, recorded by Dr. Leach, several 
females have been procured by the Rev. Hamlet Clark from the neighbourhood of Carlisle; 
Mr. R. H. Meade also has received specimens of it from Mr. Newman, which were found in 
lanes near Hastings in the autumn of 1855; and the Rev. O. P. Cambridge took an adult 
male early in January, 1857, from a rabbit-earth in Dorsetshire.
