LengtB of an adult male 4"2 mm. ; of large females without 

 raarsupium 7 mm. 



Occurrence. — From various localities in Denmark I have seen 

 a large number of specimens ; it seems to be rather common in 

 Kattegat and around our Islands between Jutland and Sweden ; 

 it is mentioned in tbe literature from the JBay of Kiel and 

 from Travemiinde. The animal figured by Sars certainly belongs 

 to this species, and according to him it is met with in Chris- 

 tianiafjord and on the southern and western coasts of ISTorway 

 northward at least to Trondhjem. Norman mentions it from 

 St. Magnus Bay, Shetland, and Th. Scott from Lerwick Bay, 

 Shetland, which in all probability are correct statements. 

 Material from Mr. Dollfus contained specimens from the Firth 

 of Clyde, western coast of Scotland ; from five localities on the 

 northern coast of France, viz. Crotoy between Boulogne and 

 Dieppe, Trouville and Villers not far from Le Havre, Carteret 

 on the western coast of Normandy, and St. Lunaire near 

 St. Malo (at the last-named place a specimen was taken in a 

 puddle on the beach) ; finally, from two localities at the western 

 coast of France, viz. Belle-Isle, off the southern coast of Brittany, 

 and Pontaillac, near Eoyau, Charente-Inferieure. In 1890 I put 

 together several other statements found in the literature (and 

 biological notes) on its occurrence in localities situated within 

 the area circumscribed by the above-named places, for instance, 

 at Portel (rather near Boulogne), on the coasts of Belgium, 

 Holland, and Great Britain ; but it is not improbable that the 

 specimens observed at some of the places mentioned by earlier 

 authors belonged to other species, especially E. afflnis, n. sp., or 

 E. inermis ; on the other hand, it occurs, in all probability, on all 

 the coasts in question. Finally, P. Gourret (Ann. Mus. Hist. 

 Nat. Mars., Zool. iv. fasc. ii. p. 13) speaks of its occurrence at 

 Marseilles; according to ' Zool. Eecord' for 1896, Sowinsky has 

 stated that it is found in the Black Sea; and Lo Bianco mentions 

 eight specimens from seven localities, partly off Capri and partly 

 from the sea between Monaco and the northern end of Corsica. 

 I am, however, inclined to think that all these statements are 

 erroneous*. 



* Gourret's papers on Crustacea are, according to statements by other 

 authors and my own judgment, far from trustworthy. It is easily seen from Lo 

 Bianco's paper that Gourret was not acquainted with several carcinological 

 papers of importance, and some of his determinations are either not correct or 

 really misleading. He undertook the naming of species of nearly all groups of 

 marine animals, but that task cannot be done well by any living zoologist.
