CRUSTACEA. 501 



Melita palmata. — Montagu, Lin. Trans., vii, p. 69, pt. 6, fig. 4. 

 Bate and Westwood, p. 337. 

 It has been taken by Dr. Leach at Plymouth. Mi'. Loughrin 

 has found it at Polperro. It is a species that is by no means 

 plentiful even where it has been found. 



Melita obtusata. — Montagu, Lin. Trans., vol. xi, p. 5, fig. 7. 

 — Bate and Westwood, p. 341. 

 The original type of this species is in the British Museum, it 

 having been taken by Col. Montagu, at Salcomb, on the south 

 coast of Devon, from which the figure given in the Sessile Eyed 

 Crustacea was taken, while the description was written from a 

 recent specimen taken in Plymouth Sound. 



Melita peoxima. — Spence Bate, Cat. Mus. Amp>h.,p. 184, pt.xxxiii, 

 fig. 4. — Bate and Westwood, p. 344. 

 This species has been taken in Plymouth Sound, and Mr. 

 Edwards, of Banff, has sent it to us from that locality. 



Melita gladiosa. — Spence Bate, Cat. B.M.,p. 185, pt. 33, f. 6. — 

 Bate and Westwood, p. 346. 

 Taken in Plymouth Sound. It resembles Gammanes podayer 

 of Mr. Milne Edwards, which undoubtedly belongs to this genus. 



Genus, M^ra. — Leach. 



First pair of antennse longer than the second, having a second 

 appendage. Second hand larger than the first. Telson double. 

 M.3Ee,a grossimana — Montagu, Lin. Trans., xi, p. 359. 



When alive the animal is very transparent, its colour being 

 faint yellow, tinted with rose. 



The type was taken by Col. Montagu, in rocky pools on the 

 south coast of Devon, but it has since been taken in Plymouth 

 Sound, Penzance, and Polperro, as well as on the coasts of Scot- 

 land and France. 



It bears a close resemblance to Mcera tenella, which Dana found 

 in the Feejee Islands. 



Genus, Eurystheus. — Spence Bate. 



Antennae su.bequally long. First pair with a second branch. 

 Hands subchelato, second larger than the first; last pair of caudal
