30 Smith and Harger — St. George's Banks Dredgings. 



podus. Second legs (figure 5) stouter; merus short triangular; 

 carpus much broader than long and only slightly produced beneath 

 the propodus; propodus about as long as the breadth of the epinieron, 

 nearly twice as long as broad ; palmary margin (figure 8) convex in 

 outline, slightly oblique, with an acute lobe and a spine at the pos- 

 terior angle, within which the tip of the dactylus closes. Third and 

 fourth legs slender and nearly naked. Basal segment in the fifth legs 

 slender, foitr times as long as broad, not wider than the merus. Sixth 

 and seventh legs slightly shorter than the fifth, the basal segments 

 posteriorly dilated and squamiform in both pairs, but broader in the 

 seventh than in the sixth. Posterior caudal stylets with the ramus 

 slightly longer than the peduncle. 



Length of largest specimen, from front of head to tip of telson, 

 about 6™"'. 



The mandibles are without palpi or molar tubercles, and in all 

 other characters the species agrees with the genus Stenothoe as 

 restricted by Boeck, but it seems to be very distinct from either of 

 the European species. 



Near Cultivator Shoal (haul Z*), 30 fathoms, soft, sandy bottom, 

 August 29. 



Syrrhoe crenulata Goes. 



Crustacea amphipoda maris Spetsbergiam alluentis, CEfversight af Kongl. Vetens- 

 kaps-Akad. Forhandlingar, Stockholm, 1865, p. 527. pi. xl, fig. 25; Boeck, Crus- 

 tacea amphipoda borealia et arctica (Vidensk.-Selskabs Forhandlinger, Christiania, 

 1870), p. 67, 1870. 

 We have also dredged this species, in 1872, in 12 fathoms in John- 

 son's Bay, near Eastport, Maine, and in 90 to 100 fathoms off Grand 

 Menan, and have examined specimens dredged, in 1873, in 30 fath- 

 oms, in Gaspe Bay, Gulf of St. Lawrence. Our specimens have all 

 been considerably larger than the one figured by Goes, but otherwise 

 agree perfectly. It seems to be an exceedingly arctic form, being 

 found in Europe from Spitzbergen to the western coast of Norway. 



Tiron acanthurus Liiijeborg.

 sarops hastata Norman, Annals and Magazine Nat. Hist., IV, ii, p. 412, pi. xxii, figs. 

 4-7, 1868. 



This species has apparently not been noticed on our coast before. 

 It has been found in Greenland, Finmark, and on the western coast 

 of Norway, while Norman's TJcessarops was from the English coast.
