The following table, based upon the text Invertebrate Zoology by R.D. Barnes (4th ed.), indicates appropriate values that were used in assigning the first 5 characters of the Element code (ELCODE) for an invertebrate animal:

The last 5 characters were based upon the sequence in which the Element was found in the appropriate standard reference for that particular taxonomic family, with the 6th and 7th values assigned to genus, and the 8th and 9th values used for species. The 10th character was a sequentially generated numeric code that identified the subspecies; a zero (0) was used if the Element was a full species.
