Examples of this species were found in hothouses in 

 Dublin during the past year (1908) by Mr. Bagnall and 

 Mr. Denis R. P. Beresford. Up to that time it had not 

 been noted in the British Islands. It was most probably 

 introduced among plants or baggage of some kind, and 

 would thus be a further instance of species of this group 

 almost certainly brought in this manner into Europe from 

 exotic regions. (See " List of British Arachnida," Proc. 

 Dors. N.H. and A.F. Club, Vol. XXIX., p. 165.) This 

 spider has been recorded from the Island of St. Vincent, 

 also from Venezuela and the Antilles. It may easily be 

 distinguished from other species of this group not only by 

 che position and number of the eyes (Diblemma Donisthorpii, 

 Cambr.), but by differences in the dorsal and ventral scutae 

 (Jschnoihyreus velox, Jackson).
