 Salpingus ornatus, sp. u. 



GIossj/j nearly nude ; head and thorax fusco-rufous ; elytra 

 nearly black, each with a testaceous curvate mark extending 

 from the shoulder to the middle, but not united to the opposite 

 one, and a large subapical but less definite spot ; antennaj 

 rod, but with three or four terminal joints piceous; legs 

 fuscous. 



Head coarsely punctured. Eyes large and prominent. 

 Thorax as long as broad, widest near the front, a good deal 

 narrowed behind, anterior angles rounded ; it is coarsely 

 punctured, some of the ])uncturcs are longitudinally con- 

 fluent. Elytra oblong, wider than the thorax at the base, 

 their sides but little rounded : they are slightly flattened 

 before the middle, wath irregular series of coarse punctures ; 

 the inner three on each elytron scarcely extend beyond the 

 middle, the fifth is more prolonged, the hind portion is quite 

 smooth. 



This is certainly nearly allied to S. jyerpiuictatus (No. 702) ; 

 the thorax is a little longer, not so broad near the front ; the 

 sides are obliquely narrowed there and the intervals between 

 the punctures are not so large ; the marks on the elytra are 

 difl'erent and their punctuation is less regular.

In June of LS94 a crab with a strange malformation was 

 brought to the Marine Laboratory, St. Andrews, by one of 

 the fishermen. Prof. M'Litush desired me to figure it. The 

 greater part of the right chela was out of sight, being situated 

 in the branchial chamber, ouly the first three joints, a small
