feet three-jointed, inner branches two-jointed; both branches 

 of tlie first pair are of nearly equal length ; the other three 

 pairs, which are nearly alike, have the inner branches con- 

 siderably shorter than the outer ; all the branches are sparingly 

 setiferous, but the terminal and lateral spines are elongate and 

 taper gradually from a moderately broad base to the sharp- 

 pointed apex ; the inner branches of the first ]iair are fur- 

 nished with a very long subapical seta in addition to the 

 terminal spine. Fifth pair small, two-branched, nearly as in 

 Attheyella cryptorum^ Brady, but the terminal and marginal 

 setae are shorter and spiniform (fig. 18). The abdomen con- 

 sists of four segments, but the iirst is composed of two 

 segments coalesced. Caudal stylets about as long as the last 

 abdominal segment. Operculum small, subconical, apex 

 acuminate. 



The male differs little from the female except in the form 

 of the anterior antennge, which are hinged and somewhat 

 dilated ; the upper margin of the third joint is produced near 

 the middle into a small lobe-like process, which forms the base 

 of a curved spiniform seta ; a sensory filament springs from the 

 upper distal angle of the same joint. A stout conical process 

 with a slightly hooked extremity arises from the proximal 

 half and extends somewhat beyond the end of the first joint 

 of the inner branches of the second pair of swimming-feet. 

 The principal branch of the fifth pair is broadly truncate at 

 the apex and provided with two short, stout, terminal spines ; 

 the small secondary branch bears an elongate setiferous 

 terminal spine and two seta? on the inner and outer margins. 

 The male abdomen consists of five segments. 



Hah. Loch Morar (a freshwater loch in Argyleshire) , in 

 material dredged in shallow water at the head of the loch and 

 also to the west of South Tarbet ; specimens were more 

 frequent in material from the latter place than from the former. 



1'his species is named in compliment to Mr. W. Anderson- 

 Smith, one of the directors of the Fishery Board for Scotland, 

 who, by his pen and otherwise, has done much to encourage 

 the study of natural history in Scotland. 



Note. — Besides Moraria Anderson- Smitki^ now described, 

 several other interesting Entomostraca were observed in the 

 material from Loch Morar, two of which may be specially 

 mentioned here, viz. : — Cyclops Ewarti, Brady, first described 

 by Dr. Brady in the Sixth Annual Report of the Fishery 

 Board for Scotland from specimens obtained in the upper 

 reaches of the Forth in November 1887 : this species has 

 not since been observed till now ; and its occurrence in Loch
