292 Dr. R. Koeliler on the Littoral Fauna of the 



Lam., and longirostris^ Edw., as very common ; Corystes 

 cassivelaunus, Penn., which lives buried in somewhat muddj 

 sand and is found abundantly at Elizabeth Castle, where 

 it digs galleries side by side with the Solens ; and, lastly, 

 Thia 2)oh'ta, Leach, which also lives in the sand and is toler- 

 ably common at La Rocque. 



Of the Macrura I will first of all indicate Gehia deltura^ 

 Leach, Callianassa suhten'anea, Leach, and Axius stirhyn- 

 chus, Leach, so as to continue the enumeration of the species 

 which dig galleries in the sand. I have found all three of 

 them at La Kocque in muddy sand, in which they bury tliem- 

 selves to a depth of several decimetres. The Geln'a is not so 

 common as the others. The Axius also sometimes occurs 

 under stones at the Greve d'Azette. 



I shall cite Pagurus Bernhardus, Forb., only as a matter of 

 form. Pagurus cuanensis and Hyndinanni^ Thomps., and 

 EujKigurus Prideauxii^ Leach, are frequently found in St. 

 Aubin's Bay, but always with the dredge. 



Palinuri and Hoviari abound, but their fishery is not very 

 active. The genus Galathea includes G. squamiferaj Leach, 

 a very common species, and G. strigosa^ Fab., of which I 

 have collected several fine specimens at La Rocque. By 

 dredging in St. Aubin's Buy I have obtained a third species, 

 which, in a former memoir, I referred with doubt to G. nexa^ 

 Embl., pointing out the differences which distinguished it 

 clearly from that species. This Galathea is G. Aadrewsii^ 

 Korm. ; moreover, Mr. Sinel has informed me that he had 

 obtained by dredging a specimen of G. nexa agreeing with the 

 type described by Embleton. 



The group of the Caridina [Salicoques) is well represented 

 by Palwmon squilla^ Fab., and serratus. Fab., and by Cran- 

 gon vulgaris, Fab., fasciatus, Risso, hisjjinosuSj Westw., tri- 

 spinosus, Hailst., and sculptiis, Bell, which live in the pools 

 of water or in the midst of the Zosteroi ; the last three species 

 are rare. Nika edulis, Risso, is not very frequent ; Panda- 

 lus annulicornisy Leach, never quits the deep water and may 

 be collected by the dredge; Athanas nitescenSj Leach, is 

 common urider stones. Uippolyte varians, Leach, and viridis, 

 Edw., abound in the meadows of Zosfera ; Hippolyte Cranchii, 

 Leach, is less abundant; 1 have collected some specimens 

 with the dredge. 



Lastly, I will note Lismata seticaudata, Risso, of which one 

 specimen was collected by Mr. Sinel in one of those baskets 

 which the fishermen em})loy in the lobster-fishery. This 

 species is regarded as peculiar to the Mediterranean. 



The group of the Schizopoda is representetl by numerous
