had ceased to be in any way suggestive of a limb. The eyes have an apical tubercle 

 carrying a setule. The first and second joints in the palp of the mandible seem 

 to be in coalescence. The pleon of the female forms a deep almost circular bowl, 

 the last three segments in coalescence constituting more than half of it. Length of 

 carapace 19 mm., greatest breadth 13 mm., second perseopod about 47 mm. long. 

 For C. spatulifrons the corresponding measurements are 19, 14, and 44 mm.

The study of this rather abundant species by numerous authors has led to its 

 receiving a considerable variety of names. These are latreillia (probably an error of 

 the press), tuberculatus, audouinii, andouinii (error of the press), cuvieri, septen- 

 trionalis, brevipes, latreillei (probably meant for a correction), danse. All are now 

 regarded as synonyms of the original E. latreillii, Guerin. In Lagerberg's useful 

 list of the synonymy the Crustacea of the Coquille are attributed to H. Milne- 

 Edwards, by mistake for Guerin, who naturally uses the form latreillii, not the 

 erroneous latreillia, which only reappears in Gay's Hist. Chile, 1849, where Nicolet 

 is pleased to refer it to Guerin' s own writings. According to the last-named author, 

 the colour in fresh (condition is greenish brown. The discussions instituted by 

 various authors make it fairly certain that the supposed specific differences depend 

 on sex and age or inconstant variation. Lagerberg had at his disposal specimens 

 varying in the length of the carapace between 8 and 87 mm., with a breadth of 

 4 '5 mm. for the smallest and of 65 mm. for the largest. The Scotia specimens do 

 not reach beyond a medium size. 



Localities. — Falkland Islands, Port Stanley, from 2 and 4 fathoms ; Port William, 

 from 6 fathoms ; Station 346, Burdwood Bank, lat. 54° 25' S., long. 57° 32' W., depth 

 56 fathoms. According to Lagerberg, the greatest depth at which this species has 

 hitherto been obtained is the 70 fathoms recorded by Miers in his Challenger report. 

 Eurypodius longirostris, Miers, was dredged in 175 fathoms.
