He records twenty-three species and describes nine as 

 new, but these have been described in earlier papers. He 

 renames the genus he had called Aspidonotus, making it 

 Aspidiophorus, as he found that the former name was 

 preoccupied.

An important paper, the most careful and scientific 

 that has appeared on the subject. He gives a good and 

 full account of the anatomy, a good bibliography, and a 

 good resume of all the systematic work on the group, 

 quoting most of the authors' original descriptions. Some 

 previously described species escaped his notice, as Ichthy- 

 dium entzii Dad. Two new genera and four new species 

 are described. The genus Gossea is framed to contain 

 Gosse's Dasydytes antenniger, Lepidoderma for Dujardin's 

 Chaetonotus squammatus, with C. rhomboides Stokes, 

 Ichthydium ocellatum Metch., and C. concinnum Stokes. 

 Lepidoderma is an unfortunate genus, as the type species 

 (C. squammatus Duj.) is spiny and a true Chaetonotus. C. 

 rhomboides Stokes is usually spiny, and /. ocellatum Metch. 

 is not stated or figured by its discoverer to have scales. 



The new species are Chaetonotus similis, C. brevi- 

 spinosus, C. Qiiacrochaetus, C. persetosus.
