Dr. L£Acn's Arrangement of the Crustacea, ác. 379 
I considered this species formerly but a mere variety of J. ni- 
ger, but later observations have induced me to consider them as 
most decidedly distinct. The strie are much stronger in this 
species, although it is a much smaller animal, and the colour is 
totally different. |

J. segmento ultimo mucronato, corpore subpellucido pallide 
subcarneo, segmentorum lateribus posticé puncto nigro. 
Long. Corp. 10 lin.

'This beautiful species I first noticed near Edinburgh, and I have 
since that time found it in the Highlands of Scotland, Wales, and 
England, under moss. It sometimes occurs in gardens. Some of 
| the: segments near the head want the red spots. The back is very 
smooth, and not striated.

aut fusco-brunneo lineis duabus rufescentibus. -
