Dall (1916) and, to a lesser extent, Iredale (1921) attempted to 

 identify the names proposed in the "Portland Catalogue," some identi- 

 fications of which I comment on in the present paper. Many of the 

 "Catalogue" names listed by Dall are nomina nuda and thus invalid. 

 These I have omitted. Others actually were taken over from Lin- 

 naeus or Born in their original sense. In some entries Lightfoot has 

 referred to the second volume of Martyn's "Universal Conchologist," 

 usually dated from 1789, but without citing a figure number. It is 

 probable that he saw the plates of this as yet unpublished volume. 



Each entry in the present paper is arranged in the following order : 

 the lot number of the "Portland Catalogue," a verbatim citation of the 

 relevant textual material, the name to be used for the taxon (in bold- 

 face type), the principal synonyms (in italics), including the most re- 

 cent ones in which the name is credited to either Solander, Humphrey, 

 or Lightfoot, and, where necessary, my own remarks. 



Lightfoot's name sometimes is enclosed in brackets to follow Recom- 

 mendation 51 A of the International Code of Zoological Nomenclature, 

 which states that the name of the author of a taxon published anon}^- 

 mously "should be enclosed in square brackets to show the original 

 anonymity." Where the trivial name has been transferred to another 

 genus I have replaced the square brackets around the author's name 

 with the required parentheses alone, to avoid the use of both square 

 brackets and parentheses. 



In all, 2 genera and 120 trivial names are considered to have been 

 first vahdly proposed in the "Catalogue." The 2 genera, Isog- 

 nomon and Placuna, have been in general use now for some time 

 although usually credited to Solander. 



Of the 120 trivial names, HI pertain to moUusks, 5 to the Cirripedia 

 (Crustacea), 2 to the Echinodermata, and 1 each to the Madreporaria 

 (Coelenterata) and Brachiopoda. 



Of these 120 names, I consider 9 to be nomina dubia, 3 junior 

 homonyms, and 46 synonyms of earlier names. This leaves 62 available 

 names that should be credited to Lightfoot as author. Forty-six of 

 these have been used in recent malacological literature, credited 

 either to Solander of Humplirey or, in a few cases, to Lightfoot. Only 

 16 (or 13%) of all the new names in the "Catalogue" have apparently 

 not come into use. Six of these I have been unable to locate as 

 accepted senior synonyms in the Hterature of the past 140 years and, 

 thus, they should be considered nomina obhta. The remaining 10, 

 in all cases but one, have been used as senior synonyms in the past 50 

 years and, thus, are available.
