CRUSTACEA MALACOSTRACA. IV. "3 



Dr. A. C. Johansen has gathered this species in two places at the east coast of Iceland, viz. in Bakke 

 Fjord, 25 — 32 fath., and 43 — 52 fath., and in Breiddals Vik, 6 fath. ; Dr. Th. Mortensen captured it at the 

 Faeroes 6 miles north-west of Kalso. 60 fath. 



Distribution. Taken several times in eastern Kattegat and the northern part of the Sound, 

 rare in south-west Kattegat and the northern part of Store Belt; depths generally 14 — 16, but varying from 

 8 to 30 — 35 fath. (Meinert, H. J. Hansen). According to G. O. Sars found along the whole coast of Norway 

 from Christiania Fjord to Vadso, 30 to 100 fath.; Norman wrote that he captured it in Throndhjems Fjord, 

 250 — 300 fath., a depth which seems to be somewhat doubtful. Norman records if from off co. Durham, 40 

 fath.; finally it has been found in the Gulf of Maine, 52 — 90 fath. (S. I. Smith).

Probably L. gracilis Stapp. and L. borcalis Stapp., established respectively on adult males and on 

 immature females captured partly in the same localities at the south coast of Novaya Zemlya, are synonyms 

 to L. villosa G. O. S. — Stappers established both species in 1908, and his full account is found in Camp. arct. 

 Due d'Orleans, Crust. Malac, 1911, p. 116 and 120, Pis. V — VI, figs. 1 — 10; PI. VII. Unfortunately Stappers 

 does not mention any serration on the lower margin of the carapace, and his figures show no trace of saw- 

 teeth, which certainly is erroneous, and in the present case it is especially unfortunate, because L. villosa, 

 as pointed out and figured by Sars, is distinguished in having nearly the whole lower margin of the carapace 

 adorned with very peculiarly formed, lamellar teeth. According to my own observation L. villosa shows 

 some individual variation in the relative length of the exopod of the uropods, which sometimes is not much 

 longer than the two proximal joints together of the endopod, sometimes reaches the middle of third joint; 

 Stappers' figures of the uropods in his two species agree rather well with these appendages in L. villosa. Sars 

 says that the two anterior free thoracic segments exhibit a structure as in L. ampidlacea, viz. "each having the 

 anterior edge emarginated in the middle, and forming on each side of the emargination a slight appressed 

 lappet." This peculiar structure is well developed in adult females of L. villosa (as figured by Sars), but in 

 females with the marsupium half developed the lappets are very feebly developed, and in females without 

 marsupium and in males lappets are indistinct or wanting — consequently the absence of lappets in Stappers' 

 specimens does not afford a specific character.
