of foot-jaws and hands agreed with the descriptions in Bell. It has 

 since been lost, and I have never met with another specimen. 



Slender-clawed Galathea (Galathea An&rewsii, mihi). Occurs 

 abundantly in deep water, as on the scallop bed at Bray, and in Dal- 

 key Sound. It never exceeds half an inch in length, I first met it 

 along with the channel-tailed shrimp, December, 1856, at Bray. 

 Spawns in February, March and April. A most variable species in 

 colour when alive. For description vide Zool. 5759. There is an 

 unnamed specimen of this species in the collection of Trinity College 

 Dublin Museum, put up by the late Dr. Ball, probably from Dalkey 

 Sound. 



Fresh-water Cray-fish (Astacus fluviatilis, Fabr.) One, at least, in 

 Bray River, Co. Wicklow, formerly also in the Liffey. Perhaps 

 introduced. This species is brought to market. 



Common Lobster (Homarus vulgaris, M.-Edw.) Among rocks, 

 very common. In spawn all the summer. Captured for market in 

 wicker pots and drum nets. The most esteemed of all the Crustacea 

 for the table here. The largest specimen I have seen was captured 

 in Kingstown Harbour, by Joseph Todhunter, Esq. ; it is now in the 

 Museum of the University of Dublin ; its length is 2|- feet, breadth 

 of carapace 5 inches, great claw 1 J foot long. 



Norway Lobster (Nephrops norvegicus, Linn, sp.) Dredged out- 

 side Poolbeg, and brought in great quantities to market, where they 

 do duty in the Dublin " shell-fish " shops as " prawns." Occasion- 

 ally drifted in at Merrion. 



Common Shrimp (Crangon vulgaris, Fabr.) Abundant in all our 

 sandy beaches, in pools and among rocks, in sandy patches, generally 

 keeping near high-water mark ; also in mouths of tidal rivers, as the 

 Dodder, at Ringsend ; ascending even into nearly fresh water. Spe- 

 cimens here are small, and not collected for the table. There is a 

 tradition that all the shrimps were destroyed in Dublin Bar in a hard 

 frost in 1740, and that they have never since grown to their former 

 size ! This species, more than any other* suffers from the heat of the 

 summer's sun. On the 8th of August last thousands could have been 

 collected dead in the dried-up strand-pools, this being almost the 

 only species of Crustacea to be met with. Spawns in March and 

 through the summer. Ova purplish. The specimens in autumn and 

 winter have a conspicuous black tail. 



Banded Shrimp (Crangon fasciatus, Risso.) This rare shrimp I 

 have met with in but one locality, a small pool in a bank near Sandy- 

 cove, at extreme low water. Spawns in May. Ova bright salmon-
