730 Beady and Norman — Monograph of the Marine and Freshwater Ostracoda 



above two named Candonai, we find them to be, unquestionably, the same species, 

 which is nearly allied to C. ZenTieri. We give Sars' description in his own words, 

 so as to do full justice to his views with respect to the several very closely allied 

 forms which he regards as distinct : — 



" Testa feminse a latere visa oblongo-subreniformis, fere duplo longior quam 

 altior, extremitate antica rotundata, postica quam in C. compressa minus expansa, 

 supine vix angulata, inferne obtusa, margine dorsali subrecto et parum mode 

 declivi, ventrali leviter sinuato ; supra visa oblongo-ovata, latitudine maxima 

 altitudine paulo minore pone medium sita, antice quam postice magis attenuata. 

 Testa maris ab eadem feminse parum discrepans, extremitate postica paulo magis 

 expansa et ad angulum inferiorum mutica. Valvulse parum insequales, Iseves, 

 nitidae, subpellucidse, sparse pilosse. Rami caudales fere recti et sensim attenuati, 

 unguibus sat fortibus et margine altero conspicue dentatis, seta marginis 

 dorsalis baud magna, ad partem ultimam tertiam rami affixa. Longitudo 

 testee, 0-90 mm." 



Habitat. — Lochgelly Loch, Fifeshire (Thomas Scott). 



Distribution. — In ditches and marshes round Christiania (G. 0. Sars).

*' Testa feminse sat compressa, a latere visa oblonga-reniformis, duplo circiter 

 longior quam altior, extremitate antice obtuse rotundata, postica sat expansa 

 adque angulum inferiorem arcuata et limbo tenui hyalino circumdata, margine 

 dorsali medio recto et paulo declivi, angulo distincto et antice et postice terminato, 

 ventrali profundius sinuato ; supra visa anguste oblonga, latitudine maxima 

 altitudine multo minore fere mediana, antice quam postice magis attenuata. 

 Testa maris ut vulgo in parte postice expansa, angulo superiore sat prominente. 

 Valvulse sparse et breviter pilosse, semipellucidse, Isevis, nitidse, margaritacese, 

 dextra sinistra nonnihil majore. Rami caudales subrecti, attenuati, unguibus 

 dimidiam rami longitudinem vix superantibus, sublsevibus, seta marginis dorsalis 

 brevi ad partem ultimam quartam rami afiixa. Longitudo testae, 0"88 mm." 



Habitat. — It is a British species, having been found thirty years ago by 

 A. M. N. in a pond at Ferry Hill, in the county of Durham, remaining since in 

 his collection as a doubtful form. 



Distribution. — Rare in marshes round Christiania (Gr. 0. Sars).
