REPORT ON THE AMPHIPODA. 559 



As important points I mention the structure of the eyes and of the nervous system, and 

 that the interior of the pereion forms a bladder containing a fluid. With the genus 

 Lanceola, Say, it agrees in the strong development of the maxillipeds, with Ci/steosoma, 

 Guerin, and Ti/ro, Milne-Edwards, in the form of the upper antennae, with the true Hyperite 

 in the shape of the urus and its appendages." 

 The type species, " Mimonectes Loveni," is very minutely dgscribed. The two other new species are 

 called Mimonectes sphxricus and " Mimonectes Steenstrupii." They all three come from the 

 Atlantic, and give the impression of being specifically very closely allied. The fact that 

 the bell or globe in the first and largest is formed by five segments, in the second by six, 

 and in the third and smallest by seven segments of the peraeon, though producing a striking 

 difference to the eye, may well be due to age or sex, and would naturally carry with it some 

 differences in the proportions of other parts of the animal.

According to the Zool. Jahresbericht fiir 1885, this paper discusses among others the eyes of 

 Gammarus, Hyperia, and Phronima.

Pages 386 to 428 embrace the Amphipoda. These are classified as follows : — 



" 1. Tribus. Laemodipoda. 1. Eam. Caprellidaj. 2. Fam. Cyamidse. 



" 2. Tribus. Crevettina. 1. Fam. Duchilidse. 2. Fam. Cheluridie. 3. Fam. Corophiidee. 

 4. Fam. Orchestiidte. 5. Fam. Ganimaridse. 



"3. Txihvsi. Hijperina. 1. Fam. Vibiliidffi. 2. Fam. Hyperidre. 3. Fam. Phronimidse. 4. Fam. 

 Platyscelidas." 



It does not seem consistent, in the definition of the Lsemodipoda to give " abdomen rudimentare 

 absque appendicibus," and to follow this by a definition of Proto, including " abdomen 

 triarticulatum, pedum paribus duobus hiarticulatis rudimentarihus." The epithet triarticu- 

 latum is not in agreement with Mayer's account of Proto, " die Anhange des eingliediigen 

 Abdomens sind in beiden Geschlechtern 2 Paare zweigliedriger Fuss-stummel." 



Caprella grandimana, Mayer, is here made a synonym of "CapreUa Dohrni," Heller. Cyamux 

 erraticus, Roussel de Vauzeme, is given as a synonym of Cyamus eeti, contrary to Liitken's 

 view. The genus Cyamus is attributed to Lamarck, instead of Latreille, the actual 

 author. 



In the "Subfam. Coropldnx (Dana) Cls.," are given " Cratippus pusillus HeU. (Colomastix pusilla 

 Grube)," and Cratippus crassimanus, Heller, but Colomastix, Grube, has priority over Cratippus, 

 Sp. Bate. To Coropliiwra acherusicum, A. Costa, is attached the synonym, "? C. crassicm-ne 

 Bruz." To Corophium crassicorne, Bruzelius, is attached the synonym " C. Bonellii Sp. B. 

 et W., 9 ." In the "Subfam. Pod.ocerinse. Cls.," to the genus Cerapus, Say, "Erichthonius 

 et Cerapodina M.-Edw., Pyctilus Dana," are given as synonyms, but the definition does not
