projecting, longitudinal, smooth and shining line. Lateral process 

 of the last segments provided with a little projecting ridge on the 

 inner surface of their lateral laminae. Colour olivaceous ; hind 

 margins ferruginous."

Our specimen agrees in almost every particular with the above 

 description ; the longitudinal line, however, appears not to extend 

 above the ninth dorsal segment, but it may be concealed under the 

 overlapping margins of the segments. In an example in Mr. 

 Saunders's collection, the longitudinal line extends from the second 

 to the eleventh segment, but in some of them it is feebly indicated. 



Sect. b. Dorsal segments without longitudinal ridge ; last segment 



compressed.

Outward aspect of S. punctatum, " of which it has also the form 

 and colour. Anterior segments and middle of the body having upon 

 the sides of the back some little ridges or projecting lines, very 

 small, transverse, subparallel, and irregular. No little ridge above 

 the insertion of the lateral laminae of the posterior segments of the 

 body. Sixth dorsal segment and the following more or less punc- 

 tured over their whole superior surface. Last segment rugose, 

 strongly marked with punctuations visible to the naked eye, at- 

 tenuated at its posterior margin."
