(n.) Any edentate animal if the family Dasypidae, peculiar to America. The body and head are incased in an armor composed of small bony plates.

There are several species, one of which (the peba) is found as far north as Texas. See Peba, Poyou, Tatouay.

Definition:
(n.) A small shield.
(n.) An old French gold coin of the value of 3s. 4d. sterling, or about 80 cents.

(5) The scutes were ingested during a period of neglect by the owner.
(6) Although different at their 3' untranslated regions, both cDNAs predict a protein with primary amino acid sequence homology to the previously described amphipathic helix-loop-helix DNA binding and dimerization motif of the Ly1-1, myc, MyoD, immunoglobulin enhancer binding, daughterless, and achaete-scute families of genes.
(7) We have determined the nucleotide sequence of two genes of the achaete - scute complex (AS-C) and show that they are homologous to two previously sequenced members of the same locus.
(8) All three encode a sequence similar to one of the conserved domains of representatives of the vertebrate myc gene family which is also present in the deduced protein sequences of the Drosophila achaete-scute gene complex.
(9) The pro-neural class of genes, for example, the achaete-scute complex, participates in the initial decision to make each uniquely positioned neuroblast or sensory organ, but are initially expressed in groups of cells.
