28 A SYNOPSIS OF THE BRITISH SYMPHVLA 



sp. n.j and another Diplopod, Napoiulus sp., new to this country. 

 In my old collection I detected single examples of S. biscutata 

 taken on the Clyde near Bishopton, and on the sea banks at 

 Hart, Co. Durham. 



During the year I have seen several specimens from an old 

 quarry and other suitable localities near Penshaw, and with 

 Mr. William Hall of Fatfield, have taken it plentifully on the 

 Durham banks of the Tees at Barnard Castle, June 4th, 1911. 



Group II. — Posterior margin of last dorsal scutum with- 

 out such cavity, but sometimes with simple depression in 

 its place. 



A. — All setcB on dorsal scuta (excepting the antero-lateral 

 pair on the first scutum) backwardly directed, rather short and 

 fusiform. Antenna' with 38 joints. 



Scutigerella hanseni sp. nov. (PL I., figs. 7-9.) 



Material. — One adult specimen. 



Length. — The specimen is distinctly contracted, and 

 measures 4*65 mm. Rather robust. 



Head somewhat ovate, about seven-eighths as long as
