NOTES ON SCOTTISH CUMACEANS 219 



Fam. IV. LAMPROPIDiE. 

 Gen. Lam props, G. O. Sars. 



(10) Lamprops fasciata, G. O. Sars. — This appears to be a 

 moderately common species on various parts of the Scottish coast, 

 especially in shallow sandy bays. The following are a few of the 

 places where it has been obtained — East Loch Tarbert, Loch Fyne ; 

 shore at Hunterston and at Inverkip, Firth of Clyde ; near Inver- 

 gordon, Cromarty Firth ; and at Muckle Ferry, Dornoch Firth ; at 

 various parts of the Firth of Forth. In this species the telson is 

 furnished with five terminal spines, two of which are shorter than 

 the others. Adult specimens appear to vary in size. 



Gen. Hemilamprops, G. O. Sars, 1882. 



(n) Hemilamprops rosea {Norman). — I have seen this 

 species on one or two occasions, and only in Clyde tow-net gather- 

 ings. It is readily distinguished from other Lampropidas, recorded 

 from our shores, by the greater number of terminal spines on the 

 telson. A single specimen was taken in the bottom tow-net between 

 Inverae and Furnace, Upper Loch Fyne. In this specimen, the 

 telson was provided with eight terminal spines. 1 Last year the 

 species was obtained in Kilbrennan Sound. 2 



(12) Hemilamprops cristata, G. O. Sars. — This species is 

 stated to have been obtained in the Firth of Clyde in i860, by the 

 late Dr. Robertson, 3 but does not appear to have been observed 

 since. The telson is furnished with three terminal spines. It must 

 be remembered, however, that the number of terminal spines in 

 this and other species is not a safe guide if the specimens be 

 immature. 



Fam. V. LEUCONID^:. 

 Gen. Leucon, Krq>yer, 1 



(13) Leucon nasicus, Kr<t>yer. — I have found this moderately 

 common in gatherings from the Firths of Forth and Clyde, as well as 

 from other parts of the Scottish coasts. The gatherings in which 

 specimens most frequently occurred were collected in comparatively 

 deep water, i.e. from 20 to 40 fathoms and upwards. Those 

 examined showed a tendency to vary in the size of the serratures of 

 the lower margins of the dorsal shield ; and the front margins of 

 the rostral projection were also, in some examples, distinctly serrate,
