218 ANNALS OF SCOTTISH NATURAL HISTORY 



(6) IPHINOE TENELLA, G. O. Sars. Rev. T. R. R. Stebbing, 

 F.R.S., in his useful work, entitled "A History of Crustacea" 

 (published in 1893), states at page 303 that Iphinoe tenella, Sars, 

 has recently been taken in the Clyde. This is a smaller species 

 than either of the other two recorded here, being scarcely more 

 than half the size of /. trispinosa. Like Cuma puhhella, it is a 

 Mediterranean species, and I have not yet observed it ; perhaps 

 its distribution is more local than some of the others. 



Gen. CUMOPSIS, G. O. Sars, 1879. 



(7) CUMOPSIS EDWARDSII (Spence Bate). This species has at 

 various times been recorded under the name of Cumopsis goodsiri. 

 It seems to prefer shallow bays where the bottom consists of fine 

 sand, or of sand and mud ; and in such situations it does not 

 appear to be very rare. I have records of its occurrence in the 

 Firth of Forth and in the Firth of Clyde. It was moderately 

 frequent in shore gathering from a sandy bay, in front of Millport, 

 Cumbrae, collected in May 1899 ; and in July of the same year it 

 was observed in a gathering collected near Ballantrae. Dr. Dohrn 

 collected this species at Millport in 1869, as well as the species to 

 be next referred to. 



(8) CUMOPSIS LONGIPES (Dohrn] (Cumopsis l&vis, G. O. Sars). 

 This Cumacean was discovered by Dr. Dohrn mixed up with the 

 more common form just referred to. In this species the cephalo- 

 thoracic shield is devoid of the lateral folds or plica which adorn 

 the shield of the other. I have obtained specimens near Millport, 

 Cumbrae ; and the late Dr. Robertson also records it from the same 

 place. 



Fam. II. VAUNTHOMPSONIID^E. 

 Gen. VAUNTHOMPSONIA, Spence Bate, 1858. 



(9) VAUNTHOMPSONIA CRISTATA, Spence Bate. I obtained this 

 species in East Loch Tarbert, Loch Fyne, in 1886; and 1 have 

 also taken it in the vicinity of May Island, Firth of Forth. I have 

 recently observed a single specimen a male in a gathering col- 

 lected off Ballantrae, Firth of Clyde, on igth July 1899, in 15-20 

 fathoms. V. cristata appears to be a somewhat rare species, but 

 being small, it may easily be overlooked. It is apparently the only 

 British representative of the family. 



Fam. III. PLATYASPID^T. 



[No Scottish representative of this family has yet been observed.]
