Ty\)e Tetrodon spengleri Bloch. 



The reasons for using the name Tetraodon for Mliller's Arothron in- 

 stead of the present group are given farther on, under the head of Tet- 

 raodon. 



If, as we suppose, Tetraodon is not available as the name of the present 

 group, the name Splimroides seems to us to have the clear right of jjri- 

 ority. In the first volume and the first half of the second volume of his 

 Histoire Naturelle des Poissons, Lacepede uses French names only, and 

 it is in this part of his work that his " Spheroide tiihercule,''^ the type of 

 his genus, " les Spheroides," occurs. This name should then be passed 

 over. Among the several reprints of Lacepede's work, there is, how- 

 ever, one now before me, in which the name of " Pillot" appears on the 

 title page as "Editeur." In this edition (volume 6, published in 1831) 

 Latin names are given to all 'the species, and the Latin form " Sphceroides 

 tuherculatus^^ is here applied. The name Spliceroides dating, then, from 

 1831, has clear priority over Cirrhisomus of Swainson (1839) and Cliei- 

 Uchthys of Miiller (1841). The name is also preferable to either of these 

 in other respects. Lacepede's diagnosis is, of course, worthless, as the 

 genus is based on a front view of a species {tubercidatus= spengleri) of 

 which he had referred a side view to the genus Tetrodon. Most of the 

 species of Spliceroides are American, as those of Tetraodon are chietly 

 East Indian. The species reach in general a much smaller size than 

 those of Lagoceplialus. 



In all our sq^ecies the nasal openings are comparatively large and 

 placed at the summit of a simple hollow papilla. In some East Indian 

 species, probably referable to this genus, this nasal papilla is two-lobed, 

 a nasal opening in each lobe.
