We present the discovery of a new quadruply lensed quasar .
The lens system , SDSS J1330+1810 at z _ { s } = 1.393 , was identified as a lens candidate from the spectroscopic sample of the Sloan Digital Sky Survey .
Optical and near-infrared images clearly show four quasar images with a maximum image separation of 1 \aas@@fstack { \prime \prime } 76 , as well as a bright lensing galaxy .
We measure a redshift of the lensing galaxy of z _ { l } = 0.373 from absorption features in the spectrum .
We find a foreground group of galaxies at z = 0.31 centred \sim 120 ^ { \prime \prime } southwest of the lens system .
Simple mass models fit the data quite well , including the flux ratios between images , although the lens galaxy appears to be \sim 1 mag brighter than expected by the Faber-Jackson relation .
Our mass modelling suggests that shear from nearby structure is affecting the lens potential .
