Index of Specific Names. 



The following index is intended to list every specific name which has been 

 used for a Recent ophiuran. The names of authors are as a rule omitted but 

 each specific name is followed by that of the genus in which the species belongs. 

 When a species has been referred to more than one genus, the generic names are 

 arranged in alphabetical order. Synonyms, nomina nuda, etc. are in italics. 

 Typographical errors and slips of the pen are surprisingly common in transcrib- 

 ing ophiuran names, even in our standard works of reference. Since such mis- 

 takes are often misleading they are included in this index, except in the following 

 cases: substitutions of ter for tr, oe for ae, th for t and i for y, and vice versa. 

 In these, and all other cases, the original spelling is accepted, unless there is 

 some very strong reason for not doing so. As regards the terminal syllable of 

 the name, the attempt is made to have adjective names agree with the generic 

 name in gender. There has been so much carelessness in this matter that many 

 specific names occur in us, a or um, and in e or is, more or less indiscriminately, 

 but only the correct form is listed in this index, quite regardless of the original 

 spelling. As for specific names, formed from personal names and ending in i 

 or ii the original spelling is adhered to, but no distinction is made between the 

 two forms, in this index. The numbers refer to the number of the species.
