i The intervals between the arrivals of the same body wave phases from distant earthquakes at a close network of stations are compared with those expected from the known surface speeds of the phases. The arrival at the station on the island of Barbados is shown to be 2.94 = 0.34 s later than expected relative to the other stations. This is believed to be due to differences in crustal structure associated with the belt of negative gravity anomalies east of the West Indian arc. A crustal section consistent with the seismic delays, gravity anomalies and seismic refraction profiles is presented.
